Fall migration of woodcock at Cape May, New Jersey Fall migration of woodcock at Cape May, New Jersey
From 1968 to 1973, 2,337 American woodcock (Philohela minor) were banded during late fall on the Cape May Peninsula of southern New Jersey. Direct recovery rates averaged 3.6 percent for hatching-year birds and 1.7 percent for adults. Distribution of recoveries indicated that Cape May migrants wintered on the coastal plain of Virginia and North Carolina. Indirect recoveries showed that...

Residues of organochlorines and heavy metals in tissues and eggs of brown pelicans, 1969-73 Residues of organochlorines and heavy metals in tissues and eggs of brown pelicans, 1969-73
Shells of brown pelican (Pelecanus occidentalis) eggs collected in South Carolina from 1969 through 1973 were significantly thinner than shells of those collected before 1947. Residues of 10 organochlorine pollutants and 10 heavy metals were found in these eggs. Total organochlorine residues were apparently magnified 23 times from fish to pelican eggs, but interpretation of...

Reproductivity of Japanese quail fed mercuric chloride in the absence of vitamin D Reproductivity of Japanese quail fed mercuric chloride in the absence of vitamin D
Mercuric chloride (HgCl2) was tested at 16 p.p.m. Hg for vitamin D sparing activity by presenting it dietarily in the presence and absence of 25-hydroxycholecalciferol (25-HCC) to Japanese quail (Coturmx c. japonica) for 25 days. No gross signs characteristic of mercury poisoning were observed, but some predictable effects of vitamin D deficiency on avian reproduction were manifested...

Status, distribution, and movements of martens in northeastern Minnesota Status, distribution, and movements of martens in northeastern Minnesota
The decline of martens in Minnesota is reviewed and a recent increase documented. Adjacent and partially overlapping home ranges of 4.3 to 19.9 sq km were determined by telemetry for a female and three males. Habitat use is described. If current trapping and timber management practices persist, martens should continue to increase.
