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,...
A review of organochlorine pesticide residues in ferruginous hawk eggs
Charles J. Henny
1985, Book chapter, Raptor Research Foundation Symposium on the Management of Birds of Prey. International Meeting. Session 1. Workshop: Status and Listing Needs of Ferruginous and Swainson's Hawks. November 1985
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...
Traditional and expanded tree pit concepts

Maximum likelihood methods for investigating reporting rates of rings on hunter-shot birds
M.J. Conroy
B.J.T. Morgan, P.M. North, editor(s)
1985, Book chapter, Statistics in Ornithology
It is well known that hunters do not report 100% of the rings that they find on shot birds. Reward studies can be used to estimate what this reporting rate is, by comparison of recoveries of rings offering a monetary reward, to ordinary rings. A reward study of American Black...
