J.-D. Lebreton, P.M. North, editor(s)
1993, Book chapter, Marked Individuals in the Study of Bird Population
Capture-recapture methods for estimating rates of immigration, emigration, and movement among geographic strata are reviewed. We discuss likelihood-based estimation methods under models incorporating Markovian and non-Markovian movement. We briefly describe a computer program developed by Brownie et al. (1992) to carry out the necessary estimation and testing....
Habitat use and survival rates of wintering American woodcocks in coastal South Carolina and Georgia
D.G. Krementz, J.T. Seginak
Jerry R. Longcore, Greg F. Sepik, editor(s)
1993, Biological Report 16
Habitat use and survival rates of radio-marked American woodcocks (Scolopax minor) were studied during the winter in coastal South Carolina (1988-89) and Georgia (1989-90). Soon after they arrived, woodcocks were captured in mist nets or in modified shorebird traps or by nightlighting. Each bird was weighed, aged, sexed,...

1993, Book chapter, Forest Remnants in the Tropical Landscape: Benefits and Policy Implications.
Central America offers a suite of neotropical habitats vital to overwintering migrant land birds. The recent decline of many forest dwelling avian migrants is believed to be related in part to neotropical deforestation and land use change. However, spatio-temporal trends in neotropical habitat availability and avian migrant habitat use are...
Critical review of the current knowledge of the biology of the American woodcock and its management on the breeding grounds
G.F. Sepik, D.G. McAuley, J. R. Longcore
Jerry R. Longcore, Greg Sepik, editor(s)
1993, Biological Report 16
We critiqued previous work on the biology and management of the American woodcock (Scolopax minor) on the breeding grounds. We determined that little is known about habitat variables and weather extremes that may limit the population. Most investigators who attempted to define habitat requirements of the woodcock used inadequate sample...
Techniques for research into woodcocks: experiences and recommendations
D.G. McAuley, J. R. Longcore, G.F. Sepik
Jerry R. Longcore, Greg F. Sepik, editor(s)
1993, Biological Report 16
We describe methods for the study of the American woodcock (Scolopax minor) at the Moosehorn National Wildlife Refuge. Described are techniques for the capture of particular age-sex cohorts during different times of the year, the aging and sexing, the evaluation of habitat components, and the estimation of population size. We...
Population trends and management opportunities for neotropical migrants
C.S. Robbins, J.R. Sauer, B.G. Peterjohn
Deborah M. Finch, Peter W. Stangel, editor(s)
1993, Book chapter, Status and Management of Neotropical Migratory Birds
The Breeding Bird Survey shows that certain Neotropical migrant songbird populations have been declining over the past 26 years. Among them are forest birds that require extensive forest on the breeding grounds and also forested habitats on tropical wintering grounds. Other species have shown significant declines only since the early...
The 'robust' capture-recapture design allows components of recruitment to be estimated
K. H. Pollock, W. L. Kendall, J.D. Nichols
J.-D. Lebreton, P.M. North, editor(s)
1993, Book chapter, Marked Individuals in the Study of Bird Population
The 'robust' capture-recapture design (Pollock 1982) allows analyses which combine features of closed population model analyses (Otis et aI., 1978, White et aI., 1982) and open population model analyses (Pollock et aI., 1990). Estimators obtained under these analyses are more robust to unequal catch ability than traditional Jolly-Seber estimators...
Behavior of radio-marked breeding American woodcocks
D.G. McAuley, J. R. Longcore, G.F. Sepik
Jerry R. Longcore, Greg F. Sepik, editor(s)
1993, Biological Report 16
During spring 1986-89, we equipped 175 male and 89 female American woodcocks (Scolopax minor) with radio transmitters. Radio-marking had little effect on behavior; within 1 day of marking, 37 of 64 (58%) displaying males were dominant and within 7 days, 138 of 157 (88%) were dominant. All females marked before...

Population trends of quails in North America

1993, Book chapter, Quail III: National Quail Symposium
We used North American Breeding Bird Survey data (1966-91) to estimate distribution, relative abundance, and populatiori trends of quails. Population trends in grassland/shrub birds sympatric with northern bobwhite (Colinus virginianus) were also examined. Northern bobwhite and scaled quail (Callipepla squamata) populations have declined since 1966. Rates of decline...

1993, Book chapter, Status and Management of Neotropical Migratory Birds.
The United States Fish and Wildlife Service coordinates several surveys that collect information on the population status of migratory birds in North America. The North American Breeding Bird Survey is the primary source of population information on nongame birds during the breeding season, and waterfowl surveys are conducted...
Survival rate estimation in the presence of tag loss using joint analysis of capture-recapture and resighting data
J.D. Nichols, J.E. Hines
J.-D. Lebreton, P.M. North, editor(s)
1993, Book chapter, Marked Individuals in the Study of Bird Population
Studies using resightings of marked birds typically make use of readily-observable tags that are not retained as well as metal legbands. We review methods for estimating survival rate with open capture-recapture / resighting models when tag loss is not negligible. All methods rely on data from double-banding studies, usually...

Many naturally occurring toxins, as well as pesticides, metals, and other compounds that occur in our environment from anthropogenic activities, stimulate or antagonize neuro-receptors to produce acute and/or chronic toxicities. Recent advances in laboratory instrumentation and the availability of a variety of radiolabeled ligands and type-specific drugs for numerous receptors...

Puerto Rican parrot (Amazona vittata) reproductive behavior: a guideline for management of active nests
K.A. Wilson
1993, Book
One explanation for the failure of intensively monitored Puerto Rican Parrot nests is that observers may lack the information needed to evaluate pair behavior and to recognize behaviors indicative of nest problems. I examined the behavior of Puerto Rican Parrots during eight non-problematic and six problematic nesting attempts to...

From 1989 to 1991,22 captive-reared Andean condors Vultur gryphus were released into three protected areas in the Andes of Colombia, South America. The goals of this reintroduction programme were to re-establish populations of these birds in protected habitat where the species had been extirpated, and to train local biologists in...
Multivariate model of female black bear habitat use for a Geographic Information System
Joseph D. Clark, James E. Dunn, Kimberly G. Smith
1993, Journal of Wildlife Management (57) 519-526
Simple univariate statistical techniques may not adequately assess the multidimensional nature of habitats used by wildlife. Thus, we developed a multivariate method to model habitat-use potential using a set of female black bear (Ursus americanus) radio locations and habitat data consisting of forest cover type, elevation, slope, aspect, distance to...
