We conducted two studies of Se exposure in captive common eiders (Somateria mollissima). In Study 1, eiders were fed diets with added Se (as L-selenomethionine) in concentrations increasing from 10 ppm to 80 ppm. In Study 2, eiders received control, low exposure (20 ppm Se), and high exposure (60 ppm Se) diets. One duck in the high exposure group in Study 2 died after 36 days. Remaining high exposure ducks in Study 2 and ducks in Study 1 were euthanized after losing 25-30% of their body weight, which occurred after 41 days and 60-78 days, respectively. Body weights did not differ between control and low exposure ducks in Study 2. At the end of Study 1, the mean Se concentration in blood was 32 ppm wet weight (ww). In Study 2, mean blood Se reached 14 ppm ww in the low exposure group and 17 ppm ww in high exposure ducks. Mean Se concentrations in liver were 1252 ppm dry weight (dw) in Study 1, and 351 and 735 ppm dw, respectively, in the low and high exposure groups of Study 2. Oxidative stress was evidenced by Se-associated effects on glutathione metabolism, but not entirely in the same manner as with previous laboratory studies in mallards. In plasma, activities of total and Se-dependent glutathione peroxidase increased with time. As Se concentrations in liver increased, Se-dependent glutathione peroxidase, glutathione reductase, oxidized glutathione, and the ratio of hepatic oxidized to reduced glutathione increased. Total and protein bound sulfhydryl concentrations, reduced glutathione, glutathione-S-transferase, and glucose-6-phosphate dehydrogenase in liver were negatively correlated with Se concentrations in the liver. In Study 2, spleen weights were significantly lower in ducks receiving 60 ppm Se than in those receiving 20 ppm. Gross lesions associated with high Se exposure included emaciation, absence of thymus, loss of nails from digits, and alopecia. Microscopic lesions included severe depletion of lymphoid organs, hepatopathy, and necrosis of feather pulp and feather epithelium. Common eiders fed high levels of Se lost weight and developed lesions similar to findings in experimental mallards, but they accumulated greater Se concentrations in tissues, particularly liver. Field studies have shown that apparently healthy seaducks generally have higher levels of Se in liver than healthy fresh water birds, but lower than the concentrations we found in our study. We conclude common eiders and probably other seaducks have a higher threshold, or adverse effect level, of Se in tissues than fresh water species.

Recently, the Chesapeake Bay had undergone an ecosystem shift and little is known about how this is affecting the seaduck populations. We are determining what are the preferred food sources of the seaducks wintering on the Bay and analyzing the factors influencing prey selection whether it is prey composition, energy assimilated, prey availability, or a combination of any or all of these factors. We have established a captive colony of surf (Melanitta perspicillata) and white-winged scoters (Melanitta fusca) as well as long-tailed ducks at Patuxent Wildlife Research Center to allow us to examine these factors in a more controlled environment. This project contains a multitude of experiments and the resultant data will be compiled into a compartmental model on the feeding ecology of seaducks wintering on the Bay. The first experiment entailed feeding groups of each species (four ducks per pen of equal sex ratio, if possible, and four pens per species) three diets varying in percent protein levels from November to February. Each diet was randomly assigned to each pen and the amount of food consumed was recorded each day. New feed was given when all existing food was consumed. Behavioral trials and blood profiles were completed on all study birds to determine the effects of the varying diets. There were no significant differences in food consumption, blood chemistry, and behavior detected at the 5% level among the diets for all three species of interest. There was a seasonal effect determined based on the food consumption data for white-winged scoters, but not for surf scoters or long-tailed ducks. The blood profiles of the surf scoters were compared to blood profiles of wild surf scoters and a there was no difference detected at the 5% level. As a health check of the ducks an aspergillosis test was run on the blood obtained during the experiment and it was found that surf scoters are more resistant to the disease than the other species. In the next two winters natural prey items available to seaducks wintering in the Chesapeake Bay will be offered on palettes to examine preference without the additional energetic costs of diving. Assimilation efficiency trials will be run on all three species to determine amount of energy the ducks obtain from each food source. Finally, using two large aquariums, prey preference will be analyzed with the additional energetic costs of diving and searching for prey. In addition, we will determine the effect of availability of a prey item on the prey selection of seaducks. We hope the model created from these experiments will allow managers to examine the effects of changes in the benthos on the seaduck populations wintering in the Chesapeake Bay.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Second North American Sea Duck Conference, November 7-11, 2005, Annapolis, Maryland.

It is well known that variation in observer ability and environmental conditions can influence the detection probability of birds in point counts, but many biologists have been reluctant to abandon point counts in favor of more intensive approaches to counting. However, over the past few years a variety of statistical and methodological developments have begun to provide practical ways of overcoming some of the problems with point counts. We describe some of these approaches, and show how they can be integrated into standard point count protocols to greatly enhance the quality of the information. Several tools now exist for estimation of detection probability of birds during counts, including distance sampling, double observer methods, time-depletion (removal) methods, and hybrid methods that combine these approaches. Many counts are conducted in habitats that make auditory detection of birds much more likely than visual detection. As a framework for understanding detection probability during such counts, we propose separating two components of the probability a bird is detected during a count into (1) the probability a bird vocalizes during the count and (2) the probability this vocalization is detected by an observer. In addition, we propose that some measure of the area sampled during a count is necessary for valid inferences about bird populations. This can be done by employing fixed-radius counts or more sophisticated distance-sampling models. We recommend any studies employing point counts be designed to estimate detection probability and to include a measure of the area sampled.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Bird Conservation Implementation and Integration in the Americas: Proceedings of the Third International Partners in Flight Conference 2002","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"U.

Resulting estimates reflect changes in numbers of birds on study areas, and such changes result from movement as well as survival and reproductive recruitment. One measure of the 'importance' of a demographic vital rate to population growth is based on temporal covariation (i.e., do changes in population growth follow changes in vital rates). If data are available to estimate vital rates or their components, then such data can be combined with capture-recapture data in order to estimate parameters of the relationship between population growth and the vital rate. These methods are illustrated using capture-recapture and nest observation data for Black-throated Blue Warblers, Dendroica caerulescens, from a long-term study at Hubbard Brook Experimental Forest, New Hampshire, USA. Population growth rate was found to be positively associated with the proportion of birds that double-brood.

Although Maine conducted surveys in the 1980s, little was known of eider molting sites in Atlantic Canada until recently, when surveys and research conducted in Quebec, Newfoundland, Labrador, Nova Scotia and Maine revealed a number of important molting sites. Sites vary in importance from a few hundred males to tens of thousands. Important sites include the western and southern coastal areas of Anticosti island (40,000 birds), Baie des Milles Vaches (9,000) in Quebec, southwestern Nova Scotia (40,000), Petit Manan Island archipelago (7,000), and Metinic Island archipelago (10,000) in Maine. Molting eider surveys conducted in Maine during the early 1980s and in the St. Lawrence in 2003-2004 revealed large flock sizes, commonly over 2,000 birds, in consistent locations annually. An estimated 40,000 males molt in Nova Scotia and 28,400 in Maine (1981 data). Surveys indicate that important sites are used consistently between years and that local movements occur. Recoveries from banded birds suggest that eiders breeding on the lower North Shore of the St. Lawrence, New Brunswick, Nova Scotia, and even Newfoundland appear to concentrate at the Petit Manan site in Maine. They also suggest inter annual movements between the Nova Scotia and Petit Manan sites. Greater understanding of the relationships between breeding, wintering, and molting sites will facilitate management of this heavily exploited sea duck.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Second North American Sea Duck Conference, November 7-11, 2005, Annapolis, Maryland.

In 2001, we documented trends in corticoid concentrations among a cohort of ten costume-reared whooping cranes subjected to ultralight aircraft training and migration. All samples were analyzed by a validated corticosterone 1251 radioimmunoassay for determination of corticoid levels. Fecal corticoid concentrations in chicks exhibited a logarithmic decline over the first 14 days after hatching (r = 0.86, p < 0.001). Fecal corticoid concentrations then stabilized at baseline levels (median 68 ng/g, range 17-186 ng/g, n = 116) during the subsequent six weeks of costume-rearing and aircraft habituation in captivity. Fecal corticoid concentrations of eight cranes increased 8-34 fold during shipment in crates to Wisconsin for field training. Increases in fecal corticoid concentrations were positively correlated with age (r = 0.81, p = 0.01), but not body weight (r = 0.44, P = 0.28) at the time of shipping. Fecal corticoid concentrations returned to baseline levels within seven days, and were sustained throughout the remainder of the training period (median 77 ng/g, range 22- 292 ng/g, n=190). Elevations in fecal corticoid concentrations were observed one (p = 0.035) and four days (p = 0.003) following physical examination and placement of leg bands compared to three days prior to the procedures (median 176 ng/g, range 116 - 553 ng/g, n = 19). Fecal corticoid concentrations decreased to pre-procedure levels within seven days. Fecal corticoid concentrations and variation during the 50 day migration period were similar to training levels in Wisconsin, except for a one day increase observed following a violent storm and escape from the temporary holding pen the preceding night (median 243 ng/g, range 228 - 280 ng/g, n = 7). There was an overall decline in fecal corticoid concentrations from the cranes during the migration (r= 0.42, p < 0.001). Acute stressors such as capture and restraint and severe storms were associated with stress responses by the cranes that varied in accordance with lasting physical or psychological stimuli. The overall process of costume-rearing, ultralight aircraft habituation, training and artificial migration was not associated with elevations in fecal corticoid concentrations suggestive of chronic stress.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the Ninth North American Crane Workshop: 17-20 January 2003, Sacramento, California","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"North American Crane Working Group","publisherLocation":"Baraboo, Wisconsin","usgsCitation":"Hartup, B., Czekala, N.M., Olsen, G.H., and Langenberg, J., 2005, Fecal corticoid monitoring in whooping cranes trained to follow ultralight aircraft, chap. of Proceedings of the Ninth North American Crane Workshop: 17-20 January 2003, Sacramento, California.","productDescription":"xi, 257","startPage":"247 (abs)","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202508,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49fee4b07f02db5f6cce","contributors":{"editors":[{"text":"Chavez-Ramirez, Felipe","contributorId":113915,"corporation":false,"usgs":true,"family":"Chavez-Ramirez","given":"Felipe","email":"","affiliations":[],"preferred":false,"id":508030,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Hartup, B.K.","contributorId":16367,"corporation":false,"usgs":true,"family":"Hartup","given":"B.K.","email":"","affiliations":[],"preferred":false,"id":330852,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Czekala, Nancy M.","contributorId":81214,"corporation":false,"usgs":true,"family":"Czekala","given":"Nancy","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":330854,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olsen, Glenn H. 0000-0002-7188-6203 golsen@usgs.gov","orcid":"https://orcid.org/0000-0002-7188-6203","contributorId":40918,"corporation":false,"usgs":true,"family":"Olsen","given":"Glenn","email":"golsen@usgs.gov","middleInitial":"H.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":330853,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Langenberg, J.A.","contributorId":91055,"corporation":false,"usgs":true,"family":"Langenberg","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":330855,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":5211327,"text":"5211327 - 2005 - Forest management under uncertainty for multiple bird population objectives","interactions":[],"lastModifiedDate":"2012-02-02T00:15:28","indexId":"5211327","displayToPublicDate":"2009-06-09T09:23:19","publicationYear":"2005","noYear":false,"publicationType":{"id":5,"text":"Book chapter"},"publicationSubtype":{"id":24,"text":"Book Chapter"},"title":"Forest management under uncertainty for multiple bird population objectives","docAbstract":"We advocate adaptive programs of decision making and monitoring for the management of forest birds when responses by populations to management, and particularly management trade-offs among populations, are uncertain. Models are necessary components of adaptive management. Under this approach, uncertainty about the behavior of a managed system is explicitly captured in a set of alternative models. The models generate testable predictions about the response of populations to management, and monitoring data provide the basis for assessing these predictions and informing future management decisions. To illustrate these principles, we examine forest management at the Piedmont National Wildlife Refuge, where management attention is focused on the recovery of the Red-cockaded Woodpecker (Picoides borealis) population. However, managers are also sensitive to the habitat needs of many non-target organisms, including Wood Thrushes (Hylocichla mustelina) and other forest interior Neotropical migratory birds. By simulating several management policies on a set of-alternative forest and bird models, we found a decision policy that maximized a composite response by woodpeckers and Wood Thrushes despite our complete uncertainty regarding system behavior. Furthermore, we used monitoring data to update our measure of belief in each alternative model following one cycle of forest management. This reduction of uncertainty translates into a reallocation of model influence on the choice of optimal decision action at the next decision opportunity.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Bird Conservation Implementation and Integration in the Americas: Proceedings of the Third International Partners in Flight Conference 2002","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"U.

Expected numbers of occurrences at points were calculated for 100 species of birds, under current habitat conditions and under habitat conditions that would result from seven alternative management scenarios for Rancho Sandoval, a cattle ranch and private nature reserve in Campeche, Mexico. Most bird species of conservation concern would benefit from management scenarios that increase the amount of forest, but the highest priority resident species would not. To balance the somewhat conflicting habitat needs of these species and the concerns of ranch managers, we recommend that forest area and connectivity be increased, and pastures be maintained but more efficiently managed to support cattle and the priority resident and migrant birds that require open habitats.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Bird Conservation Implementation and Integration in the Americas: Proceedings of the Third International Partners in Flight Conference 2002","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"U.

However, unless management simply is directed at rare species it may not be clear which habitats or management options are best. A standard, quantifiable measure to compare the significance of different tracts of land or competing management techniques for avian conservation would benefit managers in decision making. I propose a standard measure that is based on the relative density of each species within a finite area and their respective regional Partners in Flight concern scores. I applied this method to > 100 reforested sites in the Mississippi Alluvial Valley that ranged in age from 2 to 32 years. The objectively determined avian conservation significance for each of these reforested sites was correlated with stand age and with my subjective assessment of 'habitat quality.' I also used this method to compare the avian conservation significance of forested habitats before and after selective timber harvest with high significance for avian conservation provided habitat for species of conservation concern. I recommend application of this methodology to other and areas under different management, to determine its usefulness at predicting avian conservation significance among habitats and at various avian densities.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Bird Conservation Implementation and Integration in the Americas: Proceedings of the Third International Partners in Flight Conference 2002","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"U.

However, the spatial and temporal variability inherent in migration presents a number of challenges to both identifying and characterizing stopover habitat. Scarce conservation resources further demand that stopover sites be classified on a scale of priority so that conservation action can proceed according to ecological value. We are applying weather surveillance radar data collected from the National Weather Service WSR-88D at Wakefield, VA, and NASA's Doppler radar, NPOL, in Oyster, VA, to identify passerine stopover sites in the lower Chesapeake Bay region and develop spatial models to characterize these sites based on relative migrant abundance and consistency of use between and within seasons. We are using the stopover patterns to generate hypotheses regarding the habitat, geographic, and stochastic factors contributing to the distribution of migrants at a regional scale. We are testing these hypotheses with detailed habitat data and ground surveys of migrating birds with the goal of creating a generalized prioritization system for stopover site conservation.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"One Hundred and Twenty-Third Stated Meeting of the American Ornithologists' Union: abstract book","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","collaboration":"Held August 23-27, 2005, at University of California, Santa Barbara","usgsCitation":"Mabey, S., Watts, B., Paxton, B., Smith, F., Truitt, B., and Dawson, D., 2005, Characterizing stopover sites of migrating passerine birds in the lower Chesapeake Bay region for conservation: an integrated radar-habitat study, chap. of One Hundred and Twenty-Third Stated Meeting of the American Ornithologists' Union: abstract book.","startPage":"138 (abstr","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":200659,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e2e4b07f02db5e4d36","contributors":{"authors":[{"text":"Mabey, S.","contributorId":50630,"corporation":false,"usgs":true,"family":"Mabey","given":"S.","email":"","affiliations":[],"preferred":false,"id":330674,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Watts, B.","contributorId":11307,"corporation":false,"usgs":true,"family":"Watts","given":"B.","email":"","affiliations":[],"preferred":false,"id":330671,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Paxton, B.","contributorId":15316,"corporation":false,"usgs":true,"family":"Paxton","given":"B.","email":"","affiliations":[],"preferred":false,"id":330672,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Smith, F.","contributorId":16131,"corporation":false,"usgs":true,"family":"Smith","given":"F.","affiliations":[],"preferred":false,"id":330673,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Truitt, B.","contributorId":72494,"corporation":false,"usgs":true,"family":"Truitt","given":"B.","email":"","affiliations":[],"preferred":false,"id":330675,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Dawson, D.","contributorId":72901,"corporation":false,"usgs":true,"family":"Dawson","given":"D.","email":"","affiliations":[],"preferred":false,"id":330676,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}} ,{"id":5211345,"text":"5211345 - 2005 - Size evolution in Goodwin’s small-eared shrew, Cryptotis goodwini","interactions":[],"lastModifiedDate":"2017-02-07T12:16:53","indexId":"5211345","displayToPublicDate":"2009-06-09T09:23:19","publicationYear":"2005","noYear":false,"publicationType":{"id":5,"text":"Book chapter"},"publicationSubtype":{"id":24,"text":"Book Chapter"},"title":"Size evolution in Goodwin’s small-eared shrew, Cryptotis goodwini","docAbstract":"Fossils of Cryptotis goodwini from Honduras indicate that body sizes of modern individuals average at least 18% larger than among members of the late Pleistocene population of this species.

Therefore, the most likely cause of this change in size ultimately was related to climatic change at the end of the Pleistocene?but to what specific factors did the species respond? I examined the possibilities that this species changed in size: to accommodate a change in temperature regime; to escape from predators; as a response to a change in intensity of interspecific competition; to take advantage of a newly abundant food resource. Based on evidence from studies of modern communities of shrews and niche partitioning, I hypothesized that size evolution in C. goodwini was directly related to changes in the community of soil and soil-surface invertebrates upon which the species depends, specifically an increase in the availability of earthworms (Annelida).","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Advances in the biology of shrews II","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"International Society of Shrew Biologists: Special publication of the International Society of Shrew Biologists","publisherLocation":"New York, NY","usgsCitation":"Woodman, N., 2005, Size evolution in Goodwin’s small-eared shrew, Cryptotis goodwini, chap. of Advances in the biology of shrews II, p. 125-138.","productDescription":"14 p.","startPage":"125","endPage":"138","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":200712,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f2e4b07f02db5ef11a","contributors":{"editors":[{"text":"Merritt, J.F.","contributorId":111933,"corporation":false,"usgs":true,"family":"Merritt","given":"J.F.","email":"","affiliations":[],"preferred":false,"id":508011,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Churchfield, S.","contributorId":112604,"corporation":false,"usgs":true,"family":"Churchfield","given":"S.","email":"","affiliations":[],"preferred":false,"id":508013,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Hutterer, R.","contributorId":112216,"corporation":false,"usgs":true,"family":"Hutterer","given":"R.","email":"","affiliations":[],"preferred":false,"id":508012,"contributorType":{"id":2,"text":"Editors"},"rank":3},{"text":"Sheftel, B.A.","contributorId":114169,"corporation":false,"usgs":true,"family":"Sheftel","given":"B.A.","email":"","affiliations":[],"preferred":false,"id":508014,"contributorType":{"id":2,"text":"Editors"},"rank":4}],"authors":[{"text":"Woodman, N. 0000-0003-2689-7373","orcid":"https://orcid.org/0000-0003-2689-7373","contributorId":104176,"corporation":false,"usgs":true,"family":"Woodman","given":"N.","affiliations":[],"preferred":false,"id":330799,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":5211312,"text":"5211312 - 2005 - Plasma lipid metabolites and refueling performance of Semi palmated Sandpipers at migratory stopovers","interactions":[],"lastModifiedDate":"2012-02-02T00:15:21","indexId":"5211312","displayToPublicDate":"2009-06-09T09:23:19","publicationYear":"2005","noYear":false,"publicationType":{"id":5,"text":"Book chapter"},"publicationSubtype":{"id":24,"text":"Book Chapter"},"title":"Plasma lipid metabolites and refueling performance of Semi palmated Sandpipers at migratory stopovers","docAbstract":"Assessing stopover habitat quality and refueling performance of individual birds is crucial to the conservation and management of migratory shorebirds. Plasma lipid metabolites indicate the trajectory of mass change in individuals and may be a more accurate measure of refueling performance at a particular site than static measures such as nutrient reserves. We measured lipid metabolites of Semipalmated Sandpipers at 4 coastal stopover sites during northward migration: Merritt Island, FL; Georgetown, SC; Pea Island, NC; and Delaware Bay, NJ. We described spatial and temporal variation in metabolic profiles among the 4 stopovers and evaluated the effects of body mass, age, and date on metabolite concentrations. Triglyceride concentration, an indicator of fat deposition, declined during the migration, whereas B-OH-Butyrate, a measure of fasting, increased. Triglyceride concentration correlated with phospholipids and inversely related to B-OH-butyrate, but was not related to body mass or age. Triglyceride levels and estimated percent fat were greater at Delaware Bay than at any stopovers to the south. Plasma metabolite profiles accurately reflected stopover refueling performance and provide an important new technique for assessing stopover habitat quality for migratory shorebirds.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"One Hundred and Twenty-Third Stated Meeting of the American Ornithologists' Union: abstract book","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","collaboration":"Held August 23-27, 2005, at University of California, Santa Barbara.","usgsCitation":"Lyons, J.E., Collazo, J., and Guglielmo, C., 2005, Plasma lipid metabolites and refueling performance of Semi palmated Sandpipers at migratory stopovers, chap. of One Hundred and Twenty-Third Stated Meeting of the American Ornithologists' Union: abstract book.","startPage":"140 (abstr","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":200661,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adce4b07f02db6864b1","contributors":{"authors":[{"text":"Lyons, J.

Reforestation efforts are currently underway, but tracts planted with slow-growing oaks maintain the structure of a grassland for 5 yr or longer, and will require at least 40 yr to resemble a mature forest. Nonetheless, it is hoped that reforestation, even in early stages, can effectively increase core area in extant tracts of mature forest by reducing higher rates of nest failure and brood parasitism often associated with forest-agriculture interfaces. To test this, we monitored nests of a mature-forest specialist, the Acadian Flycatcher, in extensive bottomland forests adjacent to agricultural fields and reforested tracts (<20 yr-old). We used an information-theoretic approach to evaluate alternative hypotheses regarding the relative impacts of agriculture and reforestation in the landscape. Controlling for year, season, and stand basal area, there was little evidence that landscape context significantly affected nest survival, although survival tended to increase with decreasing amounts of agriculture. The probability of brood parasitism increased with greater proportions of open habitats in the landscape. There was much stronger support for the hypothesis that parasitism rates depended on the sum of agricultural and reforested tracts, rather than on the amount of agriculture alone. Thus, reforested tracts are not expected to have the desired effect of reducing parasitism rates in the adjacent mature forest until several decades have passed.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"One Hundred and Twenty-Third Stated Meeting of the American Ornithologists' Union: abstract book","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","collaboration":"Held August 23-27, 2005, at University of California, Santa Barbara.

Prioritization of species requires ranking and analysis of species by magnitude of population trend, but often magnitude of trend is a misleading measure of actual decline when trend is poorly estimated. Aggregation of population information among regions is also complicated by varying quality of estimates among regions. Hierarchical models provide a reasonable means of accommodating concerns about aggregation and ranking of quantities of varying precision. In these models the need to consider multiple scales is accommodated by placing distributional assumptions on collections of parameters. For collections of species trends, this allows probability statements to be made about the collections of species-specific parameters, rather than about the estimates. We define and illustrate hierarchical models for two commonly encountered situations in bird conservation: (1) Estimating attributes of collections of species estimates, including ranking of trends, estimating number of species with increasing populations, and assessing population stability with regard to predefined trend magnitudes; and (2) estimation of regional population change, aggregating information from bird surveys over strata. User-friendly computer software makes hierarchical models readily accessible to scientists.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Bird Conservation Implementation and Integration in the Americas: Proceedings of the Third International Partners in Flight Conference 2002","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"U.

A total of 21 surf scoters were instrumented during five years (2001-05) and 32 black scoters were instrumented during three years (2002-04) with implanted PTT 100 satellite transmitters (39 g) with external antenna. Nesting habitat of black scoters was more open than surf scoters (44% vs. 11%), whereas nesting habitat for surf scoters was located in more forested areas (66% vs. 20%). Locations of black scoters in breeding areas on average were at significantly higher latitude and lower elevations than sites used by surf scoters. Satellite telemetry determined that James Bay was the major molting area for male black and surf scoters, although some males molted along the coast of Labrador-Newfoundland. Black scoters instrumented on the Restigouche River, which is a major staging area, were widely distributed along the Atlantic Coast from Cape Cod to Georgia during winter. Major wintering areas for black scoters were Cape Cod (Martha's Vineyard and Nantucket Island), Long Island, and New Jersey. In these northern marine wintering areas, black scoters were located farther from shore (4.2 km) and in deeper water (8.3 m) than black scoters in more southern estuarine areas, where distance from shore was 3.1 km and water depth was 5.2 m. Surf scoters instrumented in Chesapeake Bay in late winter showed a strong tendency to return to the Bay the following winter after they had migrated to and from breeding areas. In Chesapeake Bay, black scoters and surf scoters were located mostly in mesohaline areas that had similar water depths (5.1 m vs. 7.5 m) and distances from shore (3.0 km vs. 2.9 km). Distance from shore and depth of water increased over time during the winter for both species. Updated information from the ARGOS Systems aboard the NOAA satellites on scoter movements was made accessible on the Patuxent Website.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Second North American Sea Duck Conference, November 7-11, 2005, Annapolis, Maryland.

Sequential mapping of the foredune crestline depicts nearly islandwide displacement during major storm events, such as in 1992, and localized displacement during alongshore passage of inshore circulation cells during other years. An instance of localized landward erosion and curvilinear displacement along approximately 400 m of foredune occurred in 1994, followed by recovery over the next nine years. Data from annual surveys and partially supported by four LIDAR flights establish that volume recovery rates in the foredune ranged from about 1.0 m3/m/yr to nearly 12.0 m3/m/yr. Analysis of the foredune morphology and location shows nearly complete recovery of foredune shape and dimension during this interval and it also demonstrates that there has been inland displacement of the foredune crestline of up to 40 m. Total volume recovery within the localized foredune erosion site was greatest, between 34 m3/m to 47 m3/m, in areas of greatest displacement and eventually contributed to creation of a foredune of similar dimension along the entire eroded zone. This process of erosion and recovery describes a mechanism for foredune dimension retention during episodic erosion and displacement and may be a model for foredune persistence accompanying barrier island migration.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Coasts under Stress II","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","collaboration":"ISBN 3-443-21141-0.

How these birds overcome their unusual height to identify, locate, track, and capture prey items is not well understood. There have been many studies on head and eye stabilization in large wading birds (herons and egrets), but the pattern of head movement and stabilization during foraging is unclear. Patterns of head movement and stabilization during walking were examined in whooping cranes at Patuxent Wildlife Research Center, Laurel, Maryland USA. Four whooping cranes (1 male and 3 females) were videotaped for this study. All birds were already acclimated to the presence of people and to food rewards. Whooping cranes were videotaped using both digital and Hi-8 Sony video cameras (Sony Corporation, 7-35 Kitashinagawa, 6-Chome, Shinagawa-ku, Tokyo, Japan), placed on a tripod and set at bird height in the cranes' home pens. The cranes were videotaped repeatedly, at different locations in the pens and while walking (or running) at different speeds. Rewards (meal worms, smelt, crickets and corn) were used to entice the cranes to walk across the camera's view plane. The resulting videotape was analyzed at the University of Maryland at Baltimore County. Briefly, we used a computerized reduced graphic model of a crane superimposed over each frame of analyzed tape segments by means of a custom written program (T. W. Cronin, using C++) with the ability to combine video and computer graphic input. The speed of the birds in analyzed segments ranged from 0.30 m/s to 2.64 m/s, and the proportion of time the head was stabilized ranged from 79% to 0%, respectively. The speed at which the proportion reached 0% was 1.83 m/s. The analyses suggest that the proportion of time the head is stable decreases as speed of the bird increases. In all cases, birds were able to reach their target prey with little difficulty. Thus when cranes are walking searching for food, they walk at a speed that permits them to keep their heads still and visual field immobile at least half the time.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the Ninth North American Crane Workshop: 17-20 January 2003, Sacramento, California","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"North American Crane Working Group","publisherLocation":"Baraboo, Wisconsin","usgsCitation":"Kinloch, M., Cronin, T., and Olsen, G.H., 2005, Head stabilization in whooping cranes, chap. of Proceedings of the Ninth North American Crane Workshop: 17-20 January 2003, Sacramento, California.","productDescription":"xi, 257","startPage":"251 (abs)","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202509,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a6be4b07f02db63d786","contributors":{"editors":[{"text":"Chavez-Ramirez, Felipe","contributorId":113915,"corporation":false,"usgs":true,"family":"Chavez-Ramirez","given":"Felipe","email":"","affiliations":[],"preferred":false,"id":508031,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Kinloch, M.R.","contributorId":54312,"corporation":false,"usgs":true,"family":"Kinloch","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":330858,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cronin, T.W.","contributorId":8959,"corporation":false,"usgs":true,"family":"Cronin","given":"T.W.","email":"","affiliations":[],"preferred":false,"id":330856,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olsen, Glenn H. 0000-0002-7188-6203 golsen@usgs.gov","orcid":"https://orcid.org/0000-0002-7188-6203","contributorId":40918,"corporation":false,"usgs":true,"family":"Olsen","given":"Glenn","email":"golsen@usgs.gov","middleInitial":"H.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":330857,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":5211320,"text":"5211320 - 2005 - Population trends of North American sea ducks based on Christmas Bird Count and Breeding Bird Survey data","interactions":[],"lastModifiedDate":"2012-02-02T00:15:25","indexId":"5211320","displayToPublicDate":"2009-06-09T09:23:19","publicationYear":"2005","noYear":false,"publicationType":{"id":5,"text":"Book chapter"},"publicationSubtype":{"id":24,"text":"Book Chapter"},"title":"Population trends of North American sea ducks based on Christmas Bird Count and Breeding Bird Survey data","docAbstract":"Due to the difficulty of conducting range-wide surveys of either breeding or wintering populations, few data are available to assess the population trends of sea ducks with confidence. We analyze sea duck data from the Audubon Christmas Bird Count (CBC) using hierarchical modeling methods that control for varying effort among circles and over time. These procedures allow us to assess early-winter relative density patterns among states and Bird Conservation Regions (BCRs) while also assessing trends in these regions and across the species North American range. Over the interval 1966-2003, continent-wide declines were observed in 1 of 11 species. Where sufficient data exist, we compare CBC results to estimates of population change derived from the USGS Breeding Bird Survey. The CBC does not effectively sample offshore populations of sea ducks; however, the CBC data can be used to assist in development of species-specific surveys, and CBC data can be used in combination with additional offshore sampling programs to better sample sea duck species.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Second North American Sea Duck Conference, November 7-11, 2005, Annapolis, Maryland.
