The Andean condor as a research surrogate for the California condor
J. W. Carpenter, F. J. Dein, D. H. Ellis
1985, Book chapter, Raptor research foundation symposium on the management of birds of prey. International meeting. Session 2. Symposium on raptor rehabilitation and captive breeding
Captive propagation of Andean Condors (Vultur gryphus) was initiated at the Patuxent Wildlife Research Center in 1966 in anticipation of the need to apply resulting techniques to the captive breeding of the endangered California Condor (Gymnogyps californianus). This report summarizes the progress made on this Andean Condor breeding and research...
Productivity, pesticides, and management of the Peregrine Falcon in Arizona
D. H. Ellis
1985, Book chapter, Raptor Research Foundation Symposium on the Management of Birds of Prey. International Meeting. Session 4.
In the decade since research commenced with the Peregrine in Arizona, over 60 sites have been identified which historically or presently are occupied by breeding pairs. Productivity was determined for about 120 breeding attempts from 1975-85. Almost all sites, for which productivity information is available for two or more years,...
An overview of raptor biology and conservation in Latin America
D. H. Ellis
1985, Book chapter, Raptor Research Foundation Symposium on the Management of Birds of Prey. International Meeting. Session 7. Western Hemisphere Meeting of the World Working Group on Birds of Prey.
Prior to the last decade, biological studies of raptorial birds in Latin America were, with a few exceptions, nonexistent. For many species all that was known was the general range and habitat type. While the logistical and political challenges are still present, the last few years has seen the opening...

Ten Ferruginous Hawk nests in northeast Oregon were studied from 1978 to 1980. Pesticide residues, eggshell thickness, and reproductive success from these nests will be reviewed. In addition, egg residues from other published studies in the Pacific Northwest and elsewhere will be discussed....
Analysis of survival data from telemetry projects
C.M. Bunck, Scott R. Winterstein, K. H. Pollock
1985, Book chapter, Raptor Research Foundation Symposium on the Management of Birds of Prey. International Meeting. Session 5. Workshop: Experimental Design and Data Analysis for Telemetry Projects. November 1985,
Telemetry techniques can be used to study the survival rates of animal populations and are particularly suitable for species or settings for which band recovery models are not. Statistical methods for estimating survival rates and parameters of survival distributions from observations of radio-tagged animals will be described. These methods have...
Case histories of organophosphate pesticides killing birds of prey in the United States
Charles J. Henny, E. J. Kolbe, E. F. Hill, L. J. Blus
1985, Book chapter, Raptor Research Foundation Symposium on the Management of Birds of Prey. International Meeting. Session 10. Second Raptor Research Foundation Conference on Raptor Conservation Techniques. November 1985
Since 1982 when secondary. poisoning of Red-tailed Hawks (Buteo jamaicensis) was documented following the recommended use of famphur on cattle, the Patuxent Wildlife Research Center has tested for organophosphate (OP) poisoning in selected birds of prey found dead. This report documents the circumstances for a number of. cases where birds...
