1985, Book chapter, Raptor Research Foundation Symposium on the Management of Birds of Prey. International Meeting. Session 4
Twenty Peregrine Falcon (Falco peregrinus) eggs (one per eyrie) were collected at random in Alaska in 1984 for organochlorine residue analysis. Prior to this study we had obtained only addled eggs which were possibly not representative of the egg-laying population if addled eggs contained different levels of organochlorines than viable...

Maximum likelihood methods for investigating reporting rates of rings on hunter-shot birds

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...

1985, Book chapter, Acta XVIII Congressus Internationalis Ornithologici, volume II
The North American Breeding Bird Survey has provided an annual index of population change since 1966. About 2400 randomly distributed roadside routes of 50 three-minute stops each provide the basic data for computer analysis. One of the reports produced shows the percentage of routes on which each species is encountered...

Seasonal Influence of Nutrients on the Physiology and Behavior of Captive Canvasbacks (Aythya valisineria)
Matthew C. Perry
1985, Book
Captive canvasbacks (Aythya valisineria) were maintained ad libitum on five diets during the winters of 1978-79 and 1979-80 to evaluate the effects of varying protein and energy levels on feed intake and condition. Diets were formulated to simulate either a natural diet high in invertebrates or one high in...
The manatee in Haiti
G. B. Rathbun, C.A. Woods, J. A. Ottenwalder
1985, Oryx (19) 234-236
The future looks bleak for the manatee population in the waters around Haiti. Results of a survey conducted by the US Fish and Wildlife Service suggest that numbers have declined drastically over the last 50 years. The best hope for the few remaining is that the hunting expertise will vanish...
Habitat Suitability Index Models: Snowshoe hare
Raymond G. Carreker
1985, FWS/OBS 82/10.101
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the Snowshoe hare (Lepus americanus). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum...

White ibises (Eudocimus albus) are members of the family Threskiornithidae in the order Ciconiiformes. They are medium-sized wading birds with a tapering decurved bill. Adults are white with black tips on the four largest primaries. Males tend to be 35% larger than females, averaging 1,036 ± 30 g (33 ±...
