The current status of woodcock and woodcock surveys in the United States The current status of woodcock and woodcock surveys in the United States
A comparison of American woodcock (Philohela minor) wing collection survey data for 1975-76 and 1976-77 showed that there was little change in the indices to breeding success and hunter success between years in the Atlantic and Central regions. The 1977 breeding population index was up 15.2 percent from 1976 in the Central region and static in the Atlantic region. There is a long-term...

Studies on the protein and sulfur amino acid requirements of young Bobwhite quail Studies on the protein and sulfur amino acid requirements of young Bobwhite quail
Four experiments were conducted with purified diets to examine the influence of protein level and to estimate the sulfur amino acid (S.A.A.) requirement of young Bobwhite quail (Colinus virginianus). These studies demonstrated (I) that 26% protein was sufficient for rapid growth when the diet was supplemented with methionine; (2) that diets containing higher levels of protein (29.3% and...

Report of the American Ornithologists' Union Committee on Conservation, 1976-77. The recovery team-recovery plan approach to conservation of endangered species; A status summary and appraisal Report of the American Ornithologists' Union Committee on Conservation, 1976-77. The recovery team-recovery plan approach to conservation of endangered species; A status summary and appraisal
The U.S. Endangered Species Act of 1973 (P.L. 93-205) identifies the U.S. Fish and Wildlife Service (USFWS), under authority delegated by the Secretary of the Interior, as the lead agency charged with the conservation of most endangered species in the United States. Some marine species are the responsibility of the Secretary of Commerce, and the responsibility for marine turtles is...

Suspected lead toxicosis in a bald eagle Suspected lead toxicosis in a bald eagle
An immature bald eagle (Haliaeetus leucocephalus) was submitted to the University of Maryland, College Park, for clinical examination. The bird was thin, had green watery feces, and was unable to maintain itself in upright posture. Following radiography, the bird went into respiratory distress and died. Numerous lead shot were recovered from the gizzard, and chemical analysis of liver...

Ticks as a factor in nest desertion of California brown pelicans Ticks as a factor in nest desertion of California brown pelicans
In summary, our observations suggest that O. denmarki may be an important environmental factor influencing the distribution and success of Brown Pelican nests in the Gulf of California. More information on these relationships may be unobtainable without seriously disturbing and destroying large numbers of nests.

Application of census techniques to habitat preservation strategy Application of census techniques to habitat preservation strategy
Island biogeography concepts applied to breeding bird populations of woodlots clearly explain why certain passerine species typical of tracts of 1 km2 or more are absent from tracts one-half or one-quarter that size. Many 'natural areas' now being preserved are too small to support the complete complement of nesting species; this is partly because little knowledge of the minimum areas...
