As part of a multi-species evaluation of the potential effects of GB-1111 on birds, red-winged blackbird eggs were collected, artificially incubated, and treated with one of five amounts of GB-1111 varying from 0 to 10 times the expected exposure from a spray application of the maximum recommended amount (X=47 l/ha, 5 gal/ac).  The application of 10 X caused a significant reduction in hatching success.  A dose-related reduction of hepatic microsomal mono-oxygenase activity (EROD) was detected.  Among body weights, skeletal measurements, and age at death, only crownrump length was different among experimental groups.  Overall, the potential hazard to embryos of a representative wetland passerine appears minimal until the application rate exceeds 3 X.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Pollution","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"6083 Albers.pdf","usgsCitation":"Albers, P., Hoffman, D.J., Buscemi, D., and Melancon, M.J., 2003, Effects of the mosquito larvicide GB-1111 on red-winged blackbird embryos: Environmental Pollution, v. 125, no. 3, p. 447-451.","productDescription":"447-451","startPage":"447","endPage":"451","numberOfPages":"5","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":17209,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6VB5-48B5M22-4&_user=696292&_coverDate=10%2F31%2F2003&_rdoc=17&_fmt=summary&_orig=browse&_srch=doc-info(%23toc%235917%232003%23998749996%23436215%23FLA%23display%23Volume)&_cdi=5917&_sort=d&_docanchor=&_ct=19&_acct=C000038819&_version=1&_urlVersion=0&_userid=696292&md5=7a2d77f9a496708d3028fe9160daee6a","linkFileType":{"id":5,"text":"html"}},{"id":201909,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"125","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac9e4b07f02db67c8e7","contributors":{"authors":[{"text":"Albers, P.H.","contributorId":26646,"corporation":false,"usgs":true,"family":"Albers","given":"P.H.","email":"","affiliations":[],"preferred":false,"id":341073,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hoffman, D.

We summarize information documenting the range expansion of Kirtland's warbler due to increased habitat management in the core breeding range in the Lower Peninsula of Michigan during 1990–2000. We collected records and conducted searches for the species in Michigan's Upper Peninsula and Wisconsin over 1978–2000. During that time 25 males were found in Wisconsin and 90 males in the Upper Peninsula. We documented colonization of Michigan's Upper Peninsula by six ringed males from the Lower Peninsula of Michigan. Four ringed birds also moved back to the core breeding range, including two males that made two-way movements between the core breeding range and the Upper Peninsula. Thirty-seven females were observed with males from 1995 to 2000, all in Michigan. Nesting activities were noted for 25 pairs and at least nine nests fledged young. One male ringed as a fledgling returned to breed in two subsequent years. After a 19-year period of population stability, the Kirtland's warbler population increased four-fold during 1990–2000, most likely in response to a tripling in habitat area. This increase in sightings and documented breeding may be related to habitat availability in Michigan's Upper Peninsula and to saturation of habitat in the main breeding range. The increase in extra-limital records during 1995–1999 corresponds to the time when the population went from the minimum to the maximum projected population densities, and a decline in natural wildfire habitat was just offset by new managed habitat for the Kirtland's warbler.</span></p>","language":"English","publisher":"Cambridge University Press","doi":"10.1017/S0030605303000632","usgsCitation":"Probst, J., Donner, D., Bocetti, C.I., and Sjogren, S., 2003, Population increase in Kirtland's warbler and summer range expansion to Wisconsin and Michigan's Upper Peninsula, USA: Oryx, v. 37, no. 3, p. 365-373, https://doi.org/10.1017/S0030605303000632.","productDescription":"9 p.","startPage":"365","endPage":"373","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":478318,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1017/s0030605303000632","text":"Publisher Index Page"},{"id":388324,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United  States","state":"Michigan, Wisconsin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -91.69189453125,\n              44.08758502824516\n            ],\n            [\n              -88.24218749999999,\n              44.308126684886126\n            ],\n            [\n              -87.451171875,\n              44.24519901522129\n            ],\n            [\n              -86.33056640625,\n              43.8028187190472\n            ],\n            [\n              -83.583984375,\n              43.54854811091286\n            ],\n            [\n              -83.1005859375,\n              44.933696389694674\n            ],\n            [\n              -83.47412109375,\n              45.81348649679973\n            ],\n            [\n              -83.47412109375,\n              46.042735653846506\n            ],\n            [\n              -84.08935546875,\n              46.45299704748289\n            ],\n            [\n              -85.078125,\n              46.7549166192819\n            ],\n            [\n              -87.802734375,\n              47.487513008956554\n            ],\n            [\n              -91.0546875,\n              46.9502622421856\n            ],\n            [\n              -92.17529296875,\n              46.63435070293566\n            ],\n            [\n              -92.3291015625,\n              46.027481852486645\n            ],\n            [\n              -92.83447265624999,\n              45.874712248904764\n            ],\n            [\n              -92.83447265624999,\n              45.583289756006316\n            ],\n            [\n              -92.74658203125,\n              44.77793589631623\n            ],\n            [\n              -91.69189453125,\n              44.08758502824516\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"37","issue":"3","noUsgsAuthors":false,"publicationDate":"2003-09-02","publicationStatus":"PW","scienceBaseUri":"4f4e4b14e4b07f02db6a47ee","contributors":{"authors":[{"text":"Probst, J.R.","contributorId":102983,"corporation":false,"usgs":true,"family":"Probst","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":341100,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Donner, D.M.","contributorId":14088,"corporation":false,"usgs":true,"family":"Donner","given":"D.M.","email":"","affiliations":[],"preferred":false,"id":341097,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bocetti, Carol I.","contributorId":60343,"corporation":false,"usgs":true,"family":"Bocetti","given":"Carol","email":"","middleInitial":"I.","affiliations":[],"preferred":false,"id":341099,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sjogren, S.","contributorId":20451,"corporation":false,"usgs":true,"family":"Sjogren","given":"S.","email":"","affiliations":[],"preferred":false,"id":341098,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Estimating the parameters of these models is an important step in applying them to real populations.  Multistate capture-recapture methods have provided a useful means for estimating survival and parameters of transition between locations or life history states but have mostly relied on the assumption that the state occupied by each detected animal is known with certainty.  Nevertheless, in some cases animals can be misclassified.  Using multiple capture sessions within each period of interest, we developed a method that adjusts estimates of transition probabilities for bias due to misclassification.  We applied this method to 10 years of sighting data for a population of Florida manatees (Trichechus manatus latirostris) in order to estimate the annual probability of transition from nonbreeding to breeding status.  Some sighted females were unequivocally classified as breeders because they were clearly accompanied by a first-year calf.  The remainder were classified, sometimes erroneously, as nonbreeders because an attendant first-year calf was not observed or was classified as more than one year old.  We estimated a conditional breeding probability of 0.31 + 0.04 (estimate + 1 SE) when we ignored misclassification bias, and 0.61 + 0.09 when we accounted for misclassification.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"6053 Kendall.pdf","usgsCitation":"Kendall, W., Hines, J., and Nichols, J., 2003, Adjusting multistate capture-recapture models for misclassification bias: manatee breeding proportions: Ecology, v. 84, no. 4, p. 1058-1066.","productDescription":"1058-1066","startPage":"1058","endPage":"1066","numberOfPages":"9","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202320,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":17148,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://www.esajournals.org/doi/abs/10.1890/0012-9658(2003)084%5B1058%3AAMCMFM%5D2.0.CO%3B2","linkFileType":{"id":5,"text":"html"}}],"volume":"84","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b03e4b07f02db698eab","contributors":{"authors":[{"text":"Kendall, W.

Changes in number of colonies over time provide a useful tool for predicting and evaluating the responses of colonial species to management and to environmental disturbance. Probabilistic Markov process models have been recently used to estimate colony site dynamics using presence–absence data when all colonies are detected in sampling efforts. Here, we define and develop two general approaches for the modelling and analysis of colony dynamics for sampling situations in which all colonies are, and are not, detected. For both approaches, we develop a general probabilistic model for the data and then constrain model parameters based on various hypotheses about colony dynamics. We use Akaike's Information Criterion (AIC) to assess the adequacy of the constrained models. The models are parameterised with conditional probabilities of local colony site extinction and colonization. Presence–absence data arising from Pollock's robust capture–recapture design provide the basis for obtaining unbiased estimates of extinction, colonization, and detection probabilities when not all colonies are detected. This second approach should be particularly useful in situations where detection probabilities are heterogeneous among colony sites. The general methodology is illustrated using presence–absence data on two species of herons. Estimates of the extinction and colonization rates showed interspecific differences and strong temporal and spatial variations.

We study this phenomenon in the context of monitoring tiger populations in India, by evaluating the 'pugmark census method' employed by wildlife managers for three decades.  We use an analytical framework of modem animal population sampling to test the efficacy of the pugmark censuses using scientific data on tigers and our field observations.  We identify three critical goals for monitoring tiger populations, in order of increasing sophistication: (1) distribution mapping, (2) tracking relative abundance, (3) estimation of absolute abundance.  We demonstrate that the present census-based paradigm does not work because it ignores the first two simpler goals, and targets, but fails to achieve, the most difficult third goal.  We point out the utility and ready availability of alternative monitoring paradigms that deal with the central problems of spatial sampling and observability.  We propose an alternative sampling-based approach that can be tailored to meet practical needs of tiger monitoring at different levels of refinement.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Animal Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1017/S1367943003003184","collaboration":"6051_Karanth.pdf","usgsCitation":"Karanth, K.U., Nichols, J., Seidensticker, J., Dinerstein, E., Smith, J., McDougal, C., Johnsingh, A., Chundawat, R.S., and Thapar, V., 2003, Science deficiency in conservation practice: the monitoring of tiger populations in India: Animal Conservation, v. 6, no. 2, p. 141-146, https://doi.org/10.1017/S1367943003003184.","productDescription":"141-146","startPage":"141","endPage":"146","numberOfPages":"6","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":478323,"rank":201,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1017/s1367943003003184","text":"Publisher Index Page"},{"id":201555,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":17147,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1017/S1367943003003184","linkFileType":{"id":5,"text":"html"}}],"volume":"6","issue":"2","noUsgsAuthors":false,"publicationDate":"2006-02-28","publicationStatus":"PW","scienceBaseUri":"4f4e4a0de4b07f02db5fd238","contributors":{"authors":[{"text":"Karanth, K.

There were no differences&nbsp;</span>in<span>&nbsp;</span>detectability<span>&nbsp;between the two observers. 3.&nbsp;</span>Detectability<span>&nbsp;estimates (SE) for one-leaf vegetative, two-leaf vegetative, and flowering/fruiting states correlated with mean size of these states and were 0.76 (0.05), 0.92 (0.06), and 1 (0.00), respectively, for previously tagged plants, and 0.84 (0.08), 0.75 (0.22), and 0 (0.00), respectively, for previously untagged plants. (We had insufficient data to obtain&nbsp;</span>a<span>&nbsp;satisfactory estimate of previously untagged flowering plants). 4. Our estimates are for&nbsp;</span>a<span>&nbsp;medium-sized plant&nbsp;</span>in<span>&nbsp;</span>a<span>&nbsp;small and intensively surveyed plot. It is possible that&nbsp;</span>detectability<span>&nbsp;is even lower for larger plots and smaller plants or smaller&nbsp;</span>life<span>-states (e.g. seedlings) and that detectabilities &lt; I are widespread&nbsp;</span>in<span>&nbsp;plant&nbsp;</span>demographic<span>&nbsp;studies. 5.&nbsp;</span>State<span>-dependent detectabilities are especially worrying since they will lead to&nbsp;</span>a<span>&nbsp;size- or&nbsp;</span>state<span>-biased sample from the&nbsp;</span>study<span>&nbsp;plot.

These comprise a very large part of the statistical models used in ecology and include t tests, simple and multiple linear regression, polynomial regression, and analysis of variance (ANOVA) and covariance (ANCOVA). There is a widely held belief that the normality assumption pertains to the raw data rather than to the model residuals. We suspect that this error may also occur in countless published studies, whenever the normality assumption is tested prior to analysis.  This may lead to the use of nonparametric alternatives (if there are any), when parametric tests would indeed be appropriate, or to use of transformations of raw data, which may introduce hidden assumptions such as multiplicative effects on the natural scale in the case of log-transformed data.  Our aim here is to dispel this myth.  We very briefly describe relevant theory for two cases of general linear models to show that the residuals need to be normally distributed if tests requiring normality are to be used, such as t and F tests.  We then give two examples demonstrating that the distribution of the response variable may be nonnormal, and yet the residuals are well behaved.  We do not go into the issue of how to test normality; instead we display the distributions of response variables and residuals graphically.","language":"English","doi":"10.1890/0012-9623(2003)84[92:NORDIG]2.0.CO;2","usgsCitation":"Kery, M., and Hatfield, J.S., 2003, Normality of raw data in general linear models:  The most widespread myth in statistics: Bulletin of the Ecological Society of America, v.  84, no. 2, p. 92-94, https://doi.org/10.1890/0012-9623(2003)84[92:NORDIG]2.0.CO;2.","productDescription":"3 p.","startPage":"92","endPage":"94","numberOfPages":"3","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":478325,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1890/0012-9623(2003)84[92:nordig]2.0.co;2","text":"Publisher Index Page"},{"id":195897,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":" 84","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afde4b07f02db696e40","contributors":{"authors":[{"text":"Kery, Marc","contributorId":168361,"corporation":false,"usgs":false,"family":"Kery","given":"Marc","affiliations":[{"id":12551,"text":"Swiss Ornithological Institute, Sempach, Switzerland","active":true,"usgs":false}],"preferred":false,"id":341001,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hatfield, Jeff S.","contributorId":95187,"corporation":false,"usgs":true,"family":"Hatfield","given":"Jeff","email":"","middleInitial":"S.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":341000,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We detected more bird species in bottomland hardwood stands than in cottonwood stands. Within hardwood stands, we detected more individuals in stands subjected to uneven-aged timber harvest than in unmanaged stands. Early in migration, avian species composition was similar in both forest types, being comprised mainly of short-distance migrants. Bird species composition in these forest types became increasingly disparate as long-distance neotropical-nearctic migrants arrived. Ten bird species were characteristic of bottomland hardwood forests, whereas eight different species were characteristic of managed cottonwood plantations. Because these two forest types supported different bird communities, both forest types provide important inland stopover habitat during migration. Silvicultural management of bottomland hardwood forests that increases their understory vegetation will provide forested habitat for a more species rich and abundant population of songbirds during migration.</span></p>","language":"English","publisher":"University of Notre Dame","doi":"10.1674/0003-0031(2003)149[0163:SBMIMA]2.0.CO;2","usgsCitation":"Wilson, R.R., and Twedt, D.J., 2003, Spring bird migration in Mississippi Alluvial Valley forests: American Midland Naturalist, v. 149 , no. 1, p. 163-175, https://doi.org/10.1674/0003-0031(2003)149[0163:SBMIMA]2.0.CO;2.","productDescription":"13 p.","startPage":"163","endPage":"175","numberOfPages":"13","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":195970,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"149 ","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699ec2","contributors":{"authors":[{"text":"Wilson, R.

Differences in the distribution  of modified wetlands may affect the predictive accuracy of waterfowl survey data if such wetlands are not distributed randomly in the landscape and if waterfowl are not distributed equally among them.  We used data  collected on thirty-eight 40-km2 plots in North Dakota to examine the distribution of modified basins relative to roadside transects and their use by five species of dabbling ducks in 1995.  The 800-m-wide transects  were subdivided into an inner 400-m transect, centered on the road, and the remaining outer transect area.  We compared the distribution of modified and natural wetland basins among three sample areas: 1) the inner 400-m wide roadside transect area, 2) the outer transect area, and 3) the  remaining area within the 40-km2 plot that was outside of the transects (outer plot).  Duck use was compared between the two transect areas.  The  plots contained 20,582 basins, of which 88.5% were unmodified, 7.5% were excavated, 3.7% were partially drained, and 0.2% were diked.  Nearly all excavated temporary (89%) and seasonal (90%) basins occurred in the inner  transect area, reflecting the high proportion of basins that would be defined as roadside ditches.  Excavated semipermanent basins were more  evenly distributed among the outer plot and two transect widths; these basins often were dugouts but also included roadside ditches.  Partially drained and diked basins also were fairly evenly distributed among the  three sample areas.  Semipermanent basins had greater use by mallards (Anas  platyrhynchos) and northern pintails (A. acuta) when they were partially drained than when they were excavated or unmodified; pintails also had  greater use of partially drained seasonal basins.  Use of wetland basins by gadwall (A. strepera), blue-winged teal (A. discors), and northern shovelers (A. clypeata) did not differ among water regimes or  modification.  We found no evidence to indicate that duck numbers determined from standard 400-m-wide roadside transects were biased relative to the larger landscape.  However, pond counts derived from such  transects were biased.  Correlations of duck numbers to pond counts that exclude ditches or temporary basins would poorly reflect the response of ducks to available water.","language":"English","publisher":"The Society of Wetland Scientists","doi":"10.1672/0277-5212(2003)023[0140:DIDOMB]2.0.CO;2","usgsCitation":"Austin, J.E., Guntenspergen, G.R., Sklebar, H.T., and Buhl, T., 2003, Differences in distribution of modified basins and ducks relative to roadside transects: Wetlands, v. 23, no. 1, p. 140-148, https://doi.org/10.1672/0277-5212(2003)023[0140:DIDOMB]2.0.CO;2.","productDescription":"9 p.","startPage":"140","endPage":"148","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true},{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":199524,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"23","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adce4b07f02db686414","contributors":{"authors":[{"text":"Austin, Jane E. jaustin@usgs.gov","contributorId":2839,"corporation":false,"usgs":true,"family":"Austin","given":"Jane","email":"jaustin@usgs.gov","middleInitial":"E.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":340923,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Guntenspergen, Glenn R. 0000-0002-8593-0244 glenn_guntenspergen@usgs.gov","orcid":"https://orcid.org/0000-0002-8593-0244","contributorId":2885,"corporation":false,"usgs":true,"family":"Guntenspergen","given":"Glenn","email":"glenn_guntenspergen@usgs.gov","middleInitial":"R.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":340926,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sklebar, H.

These experiments reveal that large birds can be readily trained to follow and most will return north (and south) in subsequent migrations unassisted.  These techniques can now be used to teach birds new (or forgotten) migration paths.  Although we are constantly improving our training techniques, we now have an operational program that can be broadly applied to those species where juveniles learn migration routes from their parents.","language":"English","publisher":"Oxford University Press","doi":"10.1641/0006-3568(2003)053[0260:MMTFOM]2.0.CO;2","usgsCitation":"Elliot, D.H., Sladen, W.J., Lishman, W.A., Clegg, K.R.,

In 1998, an initial assessment of the possible contribution of metal pollution to declining heron populations in Chesapeake and Delaware Bays was conducted.  Study sites included two heronries in industrialized locations (Pea Patch Island, DE and Baltimore Harbor, MD), and a reference site (Holland Island) remotely located in the southern Chesapeake Bay.  Concentrations of 19 metals, metalloids, and trace elements were examined in blood and breast feathers of 14-16 day old nestling black-crowned night-herons.  Metal concentrations in blood were low and showed few site differences, though mercury was elevated at Pea Patch Island as compared to other sites.  In feathers, metal concentrations appeared to be in the low to moderate range at all sites, though limited data exist for interpreting pollutant concentrations in feathers of nestling wading birds.  Where differences were detected, concentrations at Pea Patch Island were consistently greater than those at Baltimore Harbor and Holland Island.  Feathers collected at Pea Patch Island had significantly greater concentrations of aluminum, barium, iron, lead, magnesium, and manganese, but were generally found to be within the range of concentrations detected in other nestling birds, where that information was available.  Based on these results, metal pollution does not appear to be an immediate threat to BCNH colonies at these two locations, though future monitoring of some elements (Pb, Mn, and Al) may be warranted.","language":"English","publisher":"Springer","doi":"10.1007/s00128-002-0203-6","usgsCitation":"Golden, N.H., Rattner, B., McGowan, P.C., Parsons, K., and Ottinger, M.A., 2003, Concentrations of metals in feathers and blood of nestling Black-Crowned Night-Herons (Nycticorax nycticorax) in Chesapeake and Delaware Bays: Bulletin of Environmental Contamination and Toxicology, v. 70, no. 2, p. 385-393, https://doi.org/10.1007/s00128-002-0203-6.","productDescription":"9 p.","startPage":"385","endPage":"393","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":387241,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"70","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b15e4b07f02db6a50d9","contributors":{"authors":[{"text":"Golden, N.

The key feature of such problems, which we exploit, is that variation in abundance induces variation in detection probability.  Thus, heterogeneity in abundance can be modeled as heterogeneity in detection probability.  Moreover, this linkage between heterogeneity in abundance and heterogeneity in detection probability allows one to exploit a heterogeneous detection probability model to estimate the underlying distribution of abundances.  Therefore, our method allows estimation of abundance from repeated observations of the presence or absence of animals without having to uniquely mark individuals in the population.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"6027_Royle.pdf","usgsCitation":"Royle, J., and Nichols, J., 2003, Estimating abundance from repeated presence-absence data or point counts: Ecology, v. 84, no. 3, p. 777-790.","productDescription":"777-790","startPage":"777","endPage":"790","numberOfPages":"14","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":197820,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":17139,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://www.esajournals.org/doi/abs/10.1890/0012-9658(2003)084%5B0777%3AEAFRPA%5D2.0.CO%3B2","linkFileType":{"id":5,"text":"html"}}],"volume":"84","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ce4b07f02db5fc99d","contributors":{"authors":[{"text":"Royle, J.

Management to stop and/or reverse this population trend has been hampered by the lack of recent information on woodcock population parameters. Without recent information on survival rate trends, managers have had to assume that the recent declines in recruitment indices are the only parameter driving woodcock declines. Using program MARK, we estimated annual survival and recovery rates of adult and juvenile American woodcock, and estimated summer survival of local (young incapable of sustained flight) woodcock banded in Michigan between 1978 and 1998. We constructed a set of candidate models from a global model with age (local, juvenile, adult) and time (year)-dependent survival and recovery rates to no age or time-dependent survival and recovery rates. Five models were supported by the data, with all models suggesting that survival rates differed among age classes, and 4 models had survival rates that were constant over time. The fifth model suggested that juvenile and adult survival rates were linear on a logit scale over time. Survival rates averaged over likelihood-weighted model results were 0.8784 +/- 0.1048 (SE) for locals, 0.2646 +/- 0.0423 (SE) for juveniles, and 0.4898 +/- 0.0329 (SE) for adults. Weighted average recovery rates were 0.0326 +/- 0.0053 (SE) for juveniles and 0.0313 +/- 0.0047 (SE) for adults. Estimated differences between our survival estimates and those from prior years were small, and our confidence around those differences was variable and uncertain. juvenile survival rates were low.
