Microhabitat characteristics were measured and their relationship with nest success evaluated. Fifty-two percent of all nesting attempts resulted in predation. Attributes of nest placement were similar between successful and unsuccessful nests, although successful nests were placed higher. Similarly, nonparasitized nests were typically higher than parasitized nests. Nests initiated late in the breeding season were placed in larger trees with higher canopy bases resulting in increased vegetation around the nest. Fifteen different tree species were used for nesting. Acadian Flycatchers chose nest trees in a nonrandom fashion, selecting Nuttall oak (Quercus nuttallii) and possumhaw (Ilex decidua) in greater proportions than their availability. However, there was no relationship between tree species used for nesting and nest success. Nest height was positively correlated with concealment at the nest site, supporting the predator-avoidance theory. No other attribute of nest placement differentiated successful nest sites, suggesting that nest predation is likely a function of random events in space and time.","language":"English","publisher":"Oxford Academic","usgsCitation":"Wilson, R., and Cooper, R., 1998, The seventy-second Christmas bird count. 302.

During the evening crepuscular period, woodcock on the wintering grounds move from forested to field habitats, presumably to feed, conduct courtship displays, roost, and avoid predators. We conducted crepuscular flight surveys and tracked radio-marked woodcock to compare the use of fields of different sizes (<5.5 ha, 5.540.0 ha, >40.0 ha) and types (seed tree-clearcuts, fallow-old fields, hayfields, pastures). Fields > 5.5 ha were used more frequently than fields <5.5 ha (P < 0.001). Seed tree-clearcuts and fallow-old fields were more frequently used than pastures (P = 0.003). Woodcock also most frequently used fields with greater foliage volume at 0.82.0 m in height and a high percentage of bare soil (P < 0.001). Nocturnal use of fields or forests by radio-marked woodcock did not differ among age or sex classes. However, females moved an average of 230 + 32.1 m between diurnal and nocturnal locations while males moved 525 + 53.1 m ( P = 0.085). Movements differed among moon phases (P < 0.003), ranging from 579 + 79.6 m during the new moon to 213 + 50.5 m during the full moon. To manage habitat on the wintering grounds, seed tree-clearcuts and fallow-old fields should be created or maintained near preferred diurnal habitats.

Plants may be exposed to metals through water, air, or soil, depending on growth form. This paper examines the influence of soil type under two regimens of water acidification on metal uptake by four species of aquatic macrophytes: smartweed (Polygonum sagittatum), burreed (Sparganium americanum), pondweed (Potamogeton diversifolius), and bladderwort (Utricularia vulgaris) in constructed, experimentally acidified wetlands. Soil types consisted of a comparatively high-metal clay or a lower-metal sandy loam. Each pond was either acidified to pH ca. 4.85.3 or allowed to remain circumneutral. Metal concentrations tended to be higher in the submerged bladderwort and pondweed than in the emergent burreed and smartweed. Soils were important to plant metal concentrations in all species, but especially in the emergents. Acidification influenced plant concentrations of some metals and was especially important in the submerged pondweed. Bioaccumulation of metals occurred for Mn, B, Sr, Ba, and Zn, compared to soil concentrations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Water, Air, and Soil Pollution","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1023/A:1005090224878","collaboration":"5249_Sparling.pdf","usgsCitation":"Sparling, D.W., and Lowe, T., 1998, Metal concentrations in aquatic macrophytes as influenced by soil and acidification: Water, Air, & Soil Pollution, v. 108, no. 1-2, p. 203-221, https://doi.org/10.1023/A:1005090224878.","productDescription":"203-221","startPage":"203","endPage":"221","numberOfPages":"19","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":200294,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":17250,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://springerlink.metapress.com/content/j2j52414677l5466/?p=d3d951be7e844dc0a6fcf937b12d4dfb&pi=9","linkFileType":{"id":5,"text":"html"}},{"id":267626,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1005090224878"}],"volume":"108","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4be4b07f02db62582a","contributors":{"authors":[{"text":"Sparling, D.

This study evaluates primary production patterns in an estuarine system (Bass Harbor Marsh, Maine) receiving low levels of anthropogenic nitrogen. Biomass, areal coverage and in situ oxygen production of green macroalgae, Ruppia maritima, and phytoplankton were measured over a growing season to determine net ecosystem production. Macroalgae and Ruppia exhibited strong seasonal biomass curves with early summer peaks; however, peak biomass of macroalgae (150 g dwt m-2) was substantially greater than Ruppia (33 g dwt m-2). Phytoplankton biomass, measured as chlorophyll a, was low (<1 ug l-1) early in the season and peaked (11 ug l-1) following a mid-summer decline in macroalgal biomass, suggesting a competitive interaction with macroalgae. Instantaneous net production rates varied over the growing season for all three primary producers. Ruppia net production ranged from near zero to 3.7 mg C g dwt-1 h-1, with higher rates during summer and much of the seasonal variability explained by temperature. Macroalgal (0.88 - 5.0 mg C g dwt-1 h-1) and phytoplankton (0 - 28 mg C m-3 h-1) net production did not exhibit any clear seasonal signal. Net primary production calculated on an areal basis demonstrated macroalgae's dominance in the lower basin of Bass Harbor Marsh, with peak summer rates (400 mg C m-2 h-1) greatly exceeding maximum rates for both Ruppia (70 mg C m-2 h-1) and phytoplankton (12 mg C m-2 h-1). When compared to other New England estuarine sites with short residence times, nutrient loading and peak green macroalgal biomass in Bass Harbor Marsh is relatively low; however, the strong dominance of opportunistic green macroalgae is a pattern that is characteristic of shallow coastal systems undergoing eutrophication.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Ecology Progress Series","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Inter-Research","doi":"10.3354/meps163089","collaboration":"5213_Kinney.pdf","usgsCitation":"Kinney, E., and Roman, C.T., 1998, The response of primary producers to nutrient enrichment in a shallow estuary: Marine Ecology Progress Series, v. 163, p. 89-98, https://doi.org/10.3354/meps163089.","productDescription":"89-98","startPage":"89","endPage":"98","numberOfPages":"10","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":479681,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3354/meps163089","text":"Publisher Index Page"},{"id":198378,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266009,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3354/meps163089"}],"volume":"163","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a6fe4b07f02db640f38","contributors":{"authors":[{"text":"Kinney, E.H.","contributorId":8202,"corporation":false,"usgs":true,"family":"Kinney","given":"E.H.","email":"","affiliations":[],"preferred":false,"id":338885,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Roman, C.

A finely laminated, organic carbon (OC) rich sapropel (unit II) was produced as a result of this anoxia. The trigger for increased OC production and development of anoxia was the spillover of saline waters through the Bosporus that probably began at ∼9.0 ka and peaked between ∼7.0 and 5.5 ka. This spillover enhanced vertical mixing and nutrient cycling and caused a short-term (2–3 kyr) burst in surface-water productivity during the early part of unit II deposition. Continued incursion of saline waters enhanced vertical stability and inhibited mixing of nutrients into surface waters, thus limiting primary production and decreasing the OC flux to sediments beginning ∼5.5 ka. Concentration, accumulation rate, and degree of preservation of organic matter all decreased in the upper part of unit II as a result of decreasing productivity, but anoxia persisted throughout most of the water column. The end of unit II sapropel deposition was synchronous across the Black Sea as the result of the first blooms of the coccolith Emiliania huxleyi, which presumably marked an increase in surface-water salinity above 11 and the beginning of unit I deposition. The high coccolith-carbonate fluxes that occurred during deposition of unit I diluted the OC concentration in the sediments, but OC accumulation rates are about the same as those in upper part of unit II.

These species have been regarded as members of an Oryzomys capito complex and for a long time were consolidated into a single entity identified as O. capito. Our study documents the following: 1. Defining the limits of species within the O. capito complex first requires a comprehensive review and rigorous definition of O. capito itself. We consider Fischer's (1814) Mus megacephalus to be valid and available, designate a neotype to bear the name, and reinstate it as a senior synonym of capito Olfers (1818). We then provide a working definition of O. megacephalus and its close relative, O. laticeps, derived from analyses of morphometric variation, estimates of geographic distributions, and evaluations of synonyms. In our view, O. megacephalus occurs in Amazonia but also extends into eastern Paraguay; its synonyms are capito Olfers (1818), cephalotes Desmarest (1819), velutinus Allen and Chapman (1893), goeldi Thomas (1897), modestus Allen (1899), and perenensis Allen (1901). Oryzomys laticeps Lund (1840) occurs in the Atlantic Forest region of eastern Brazil. We designate a lectotype for laticeps and allocate the names saltator Winge (1887) and oniscus Thomas (1904) as synonyms. 2. We provide the first comprehensive taxonomic revision of Oryzomys yunganus Thomas (1902). Its range covers tropical evergreen rainforest formations in the Guiana region and the Amazon Basin where, as documented by voucher specimens, it has been collected at the same localities as O. megacephalus, O. nitidus, and O. tern of carotid arterial circulation, occlusal patterns of second upper and lower molars, cranial proportions, and chromosomal features. Appreciable intraspecific geographic variation occurs in diploid number of chromosomes and frequency of occurrence of the hypothenar plantar pad, but sampling inadequacies obscure the significance of this variation. Large body size is characteristic of populations in the western Amazon Basin and in the tepui region of eastern Venezuela; smaller size characterizes populations in the Guianas and along the eastern margin of the Amazon Basin. No other scientific name has been correctly associated with the species. Samples from Mirador, Palmera, and Mera in the western Andean foothills of central Ecuador possess a combination of pelage, cranial, and dental traits that distinguish them from all samples of O. yunganus. These specimens are the basis for a new species we describe here, one that is more closely related to O. yunganus than to any other member of the former O. 'capito' complex. 3. We redescribe Oryzomys bolivaris (reviewed by Pine, 1971, under the name O. bombycinus), amplify its geographic range, and contrast it with O. talamancae and O. alfaroi, two sympatric congeners often confused with it. A distinctive set of morphological traits allows unambiguous identification of specimens belonging to O. bolivaris. It is a trans-Andean species recorded from very wet tropical evergreen rainforests extending from eastern Honduras and Nicaragua through Costa Rica and Panama to western Colombia and Ecuador. Allen's (1901) bolivaris is the oldest name for this species; castaneus Allen (1901), rivularis Allen (1901), bombycinus Goldman (1912), alleni Goldman (1915), and orinus Pearson (1939) are synonyms. 4. We revise the definition of Oryzomys talamancae Allen (1891) provided by Musser and Williams (1985), document additional specimens, describe karyotypes from Ecuadoran and Venezuelan samples, and contrast its morphology, chromosomes, and distribution with those of O. alfaroi and O. megacephalus.

Survey staff assessed conditions on 244 sites within 36 back-country campgrounds, including 113 individual campsites, 43 group campsites, and 88 shelters. Site conditions are generally quite good. Site size and other areal measures of disturbance are exceptionally small attributed to the placement of most sites on cut-and-fill constructed ?benches? within sloping terrain. Relational analyses revealed that campsites in Spruce and Fir forests and under more open forest canopies have significantly lower areal measures of disturbance. Areal disturbance is also reduced on sites where shelters and picnic tables are present, suggesting that these facilities act to concentrate visitor use. Site locational attributes, such as intersite visibility and proximity to trails, indicate a low potential for solitude within some campgrounds. Recommendations regarding site number, distribution, arrangement, facilities, maintenance, and monitoring are offered for management consideration.

In the 1960's, Canada goose flocks were restored to historic breeding ranges in the United States and southern Canada to enhance recreational opportunity for observation and harvest. These populations of southern breeding geese have rapidly expanded, increasing conflicts with social and economic interests and causing the Midwinter Waterfowl Survey to be less effective as a management tool to monitor migrant populations. Wildlife agencies need methods to control local, southern breeding geese that reduce conflicts while providing adequate protection to populations of northern breeding geese. New techniques have been developed using mark-resight data from neck-banded geese to estimate distribution and population size during the late summer, fall, and mid-winter. Survival and movement rates can be estimated over special early or late hunting seasons, traditional fall-winter hunting season, and nonharvest periods. Direct recovery rates can be estimated for special and traditional harvest periods and these recovery rates can be related to survival and movement rates. Changes in harvest regulations can be related to changes in recovery, survival, and movement rates for specific cohorts of Canada geese. These techniques can be used to monitor population status and determine more appropriate harvest strategies.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Biology and management of Canada geese: proceedings of the International Canada Goose Symposium","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisherLocation":"Milwaukee, WI","collaboration":"OCLC: 41657065 ; Papers and abstracts from the symposium held in Milwaukee, Wisconsin, April 23-25, 1998","usgsCitation":"Hestbeck, J., 1998, Estimating population parameters for northern and southern breeding populations of Canada geese, chap. of Biology and management of Canada geese: proceedings of the International Canada Goose Symposium, p. 445-453.","productDescription":"xvii, 515","startPage":"445","endPage":"453","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":203209,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a7ee4b07f02db648639","contributors":{"editors":[{"text":"Rusch, Donald H.","contributorId":111715,"corporation":false,"usgs":true,"family":"Rusch","given":"Donald","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":507807,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Samuel, Michael D. msamuel@usgs.gov","contributorId":1419,"corporation":false,"usgs":true,"family":"Samuel","given":"Michael","email":"msamuel@usgs.gov","middleInitial":"D.","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":true,"id":507805,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Humburg, Dale D.","contributorId":79357,"corporation":false,"usgs":false,"family":"Humburg","given":"Dale","email":"","middleInitial":"D.","affiliations":[{"id":13073,"text":"Ducks Unlimited, Inc.","active":true,"usgs":false}],"preferred":false,"id":507806,"contributorType":{"id":2,"text":"Editors"},"rank":3},{"text":"Sullivan, Brian D.","contributorId":114052,"corporation":false,"usgs":true,"family":"Sullivan","given":"Brian","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":507808,"contributorType":{"id":2,"text":"Editors"},"rank":4}],"authors":[{"text":"Hestbeck, J.B.","contributorId":107802,"corporation":false,"usgs":true,"family":"Hestbeck","given":"J.B.","affiliations":[],"preferred":false,"id":330413,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":5211127,"text":"5211127 - 1998 - Field evidence for linking Altosid applications with increased amphibian deformities in southern leopard frogs [abstract]","interactions":[],"lastModifiedDate":"2015-01-21T10:59:23","indexId":"5211127","displayToPublicDate":"2009-06-09T09:23:19","publicationYear":"1998","noYear":false,"publicationType":{"id":5,"text":"Book chapter"},"publicationSubtype":{"id":24,"text":"Book Chapter"},"title":"Field evidence for linking Altosid applications with increased amphibian deformities in southern leopard frogs [abstract]","docAbstract":"During the summer of 1997 we repeatedly sprayed Altosid, a formulation of 4% methoprene used for mosquito control, on six constructed macrocosms. Six additional macrocosms were sprayed with Abate4E, containing the organophosphate pesticide temephos, and six were sprayed with water (controls). The wetlands were created on an impermeable foundation for research purposes and averaged 215 m2 in area and 0.5 m deep. Application rates and frequency of Abate4E and Altosid followed label directions and mimicked procedures for mosquito control in National Wildlife Refuges. In early September juvenile frogs and metamorphing tadpoles were collected with dip nets from each pond and examined for deformities. In all, 91 juveniles and metamorph southern leopard frogs (Rana utricularia) were collected from Altosid sprayed wetlands with 14 (15%) demonstrating deformities. Seventyseven juveniles and metamorphs were collected from control wetlands with three (4%) showing deformities. Only six juveniles and metamorphs were collected from Abate4E wetlands and none showed deformities. Deformities included missing or deformed hind limbs (9 of 10 involving only the right hind limb), missing eyes, and abnormal color. The differences in rate of deformities was dependent on treatment (X2=6.44, p< 0.02). The number of leopard frogs caught per unit effort (tadpoles and juveniles) differed among treatments (p=0.032) with Abate4E wetlands producing fewer individuals per capture effort than either Altosid or control wetlands.

To explain the declining number of wintering geese in the Chesapeake and Carolina regions and the increasing number in the mid-Atlantic region from 1984 to 1989, I tested several hypotheses concerning regional differences in production, survival, and movement. The observation of migratory geese neckbanded in northern Quebec and throughout the winter grounds, and the lack of a regional difference in the proportion of young in the harvest, indicated that regional differences in production on the breeding grounds was unlikely to explain the observed changes in mid-winter number. Average annual survival rates were highest for geese in the Chesapeake and lowest for geese in the mid-Atlantic indicating that differential survival between regions did not cause the large changes in mid-winter numbers between regions. Geese were more likely to move to, and remain in, the Chesapeake than any other region. Estimated movement patterns did not match observed changes in mid-winter counts. Consequently, the observed changes in number of wintering geese from 1984 to 1989 could not be explained by my analyses of differential production, survival, or movement. The survival and movement analyses, however, were based largely on data from migratory, northern breeding geese. In the aerial Midwinter Waterfowl Survey, migratory, northern-breeding geese cannot be distinguished from local, southern-breeding geese. The changes in mid-winter numbers may result from declining numbers of migratory, northern-breeding geese wintering in the Chesapeake and Carolinas and increasing numbers of local, southem-breeding geese remaining in the mid-Atlantic.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Biology and management of Canada geese: proceedings of the International Canada Goose Symposium","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisherLocation":"Milwaukee, WI","collaboration":"OCLC: 41657065 ; Papers and abstracts from the symposium held in Milwaukee, Wisconsin, April 23-25, 1998","usgsCitation":"Hestbeck, J., 1998, Changing number of Canada geese wintering in different regions of the Atlantic Flyway, chap. of Biology and management of Canada geese: proceedings of the International Canada Goose Symposium, p. 211-219.","productDescription":"xvii, 515","startPage":"211","endPage":"219","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":203208,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48cee4b07f02db54545e","contributors":{"editors":[{"text":"Rusch, Donald H.","contributorId":111715,"corporation":false,"usgs":true,"family":"Rusch","given":"Donald","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":507803,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Samuel, Michael D. msamuel@usgs.gov","contributorId":1419,"corporation":false,"usgs":true,"family":"Samuel","given":"Michael","email":"msamuel@usgs.gov","middleInitial":"D.","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":true,"id":507801,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Humburg, Dale D.","contributorId":79357,"corporation":false,"usgs":false,"family":"Humburg","given":"Dale","email":"","middleInitial":"D.","affiliations":[{"id":13073,"text":"Ducks Unlimited, Inc.","active":true,"usgs":false}],"preferred":false,"id":507802,"contributorType":{"id":2,"text":"Editors"},"rank":3},{"text":"Sullivan, Brian D.","contributorId":114052,"corporation":false,"usgs":true,"family":"Sullivan","given":"Brian","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":507804,"contributorType":{"id":2,"text":"Editors"},"rank":4}],"authors":[{"text":"Hestbeck, J.B.","contributorId":107802,"corporation":false,"usgs":true,"family":"Hestbeck","given":"J.B.","affiliations":[],"preferred":false,"id":330412,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":5211231,"text":"5211231 - 1998 - The North American Amphibian Monitoring Program.

[abstract]","docAbstract":"The North American Amphibian Monitoring Program has been under development for the past three years. The monitoring strategy for NAAMP has five main prongs: terrestrial salamander surveys, calling surveys, aquatic surveys, western surveys, and atlassing. Of these five, calling surveys were selected as one of the first implementation priorities due to their friendliness to volunteers of varying knowledge levels, relative low cost, and the fact that several groups had already pioneered the techniques involved. While some states and provinces had implemented calling surveys prior to NAAMP, like WI and IL, most states and provinces had little or no history of state/provincewide amphibian monitoring. Thus, the majority of calling survey programs were initiated in the past two years. To assess the progress of this pilot phase, a program review was conducted on the status of the NAAMP calling survey program, and the results of that review will be presented at the meeting. Topics to be discussed include: who is doing what where, extent of route coverage, the continuing random route discussions, quality assurance, strengths and weaknesses of calling surveys, reliability of data, and directions for the future. In addition, a brief overview of the DISPro project will be included. DISPro is a new amphibian monitoring program in National Parks, funded by the Demonstration of Intensive Sites Program (DISPro) through the EPA and NPS. It will begin this year at Big Bend and Shenandoah National Parks. The purpose of the DISPro Amphibian Project will be to investigate relationships between environmental factors and stressors and the distribution, abundance, and health of amphibians in these National Parks. At each Park, amphibian long-term monitoring protocols will be tested, distributions and abundance of amphibians will be mapped, and field research experiments will be conducted to examine stressor effects on amphibians (e.g., ultraviolet radiation, contaminants, acidification).","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Midwest Declining Amphibians Conference, a joint meeting of the Great Lakes and Central Division Working Groups of the Declining Amphibian Populations Task Force, March 20 & 21, 1998","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Milwaukee Public Museum","publisherLocation":"Milwaukee, Wisconsin","collaboration":"OCLC: 42917615; published as OCLC: 45165303 ; see MERRIAM QL667 .I58 2000 Investigating amphibian declines : proceedings of the 1998 declining amphibians conference","usgsCitation":"Griffin, J., 1998, The North American Amphibian Monitoring Program.

In three expeditions (1994, 1995, and 1997), we located over 120 Saker Falcon eyries in Mongolia. Over 20% of these were on man-made structures. Because so many falcons were already nesting on artificial supports, we decided that the creation of artificial eyries on man-made supports would be the most efficient means of expanding saker populations. Two other factors also recommended the creation of artificial eyries. First, most of Mongolia is open steppe with good prey populations but without trees or cliffs that might support falcon eyries. Second, in the open habitat, man-made supports are often available but nests are often absent. In 1997, we created 65 new nest sites and enlarged or modified another 15 previously used falcon eyries. This paper reports the extreme variety in sites used by Saker Falcons in Mongolia, and occupancy rates on artificial eyrie supports.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Raptor Research Foundation Annual Meeting, Program and Abstracts, Ogden, Utah, 30 September-4 October","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","usgsCitation":"Ellis, D.H., Tsengag, P., and Whitlock, P., 1998, Eyrie enhancement measures to bolster Saker falcon populations in Mongolia, chap. of Raptor Research Foundation Annual Meeting, Program and Abstracts, Ogden, Utah, 30 September-4 October.","startPage":"18 (abs)","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202889,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a09e4b07f02db5fb016","contributors":{"authors":[{"text":"Ellis, D.
