Body weights of newly hatched Anatidae Body weights of newly hatched Anatidae
As early as 1928 (E.C. Meyers, Auk, 45: 334-388, 1928) investigators realized the importance of bird weights and appealed to ornithologists to record and publish records of these. Practically all of the weights of waterfowl that have been published, however, have been of adults or grown young (see F.H. Kortright, The ducks, geese and swans of North America, Amer. Wildl. Inst., 1943, pp...

Rodent repellents, correlation between chemical structure and rodent repellency of benzoic acid derivatives Rodent repellents, correlation between chemical structure and rodent repellency of benzoic acid derivatives
Sixty-five benzoic acid derivatives were either prepared or obtained from commercial concerns, tested for rat repellency, and their indices of repellency computed. The data from these tests were considered analytically for any correlation between chemical structure and rat repellency. The results suggest a qualitative relationship which is useful in deciding probability of repellency in...

Care of captive woodcocks Care of captive woodcocks
Numbers of American woodcocks (Philohela minor) were held in cages for experimental work lasting several months. Injuries caused by birds attempting to flush were greatly reduced by clipping feathers from one wing, by making cage walls opaque, and by using high cages or false ceilings of fabric. Size of cage was found not to be important, to judge from weight changes, so long as ample...

Bird mortality after spraying for Dutch elm disease with DDT Bird mortality after spraying for Dutch elm disease with DDT
In Hanover, New Hampshire, where elms were sprayed with DDT, 151 dead birds were found; 10 dead birds were found in Norwich, Vermont, where no DDT was used. Chemical analyses of dead birds, observation of symptoms of DDT poisoning, and a population decline after spraying all indicate severe mortality among certain species in Hanover.

Some diseases and parasites of captive woodcocks Some diseases and parasites of captive woodcocks
Observations were made concerning the diseases and parasites of a group of woodcocks (Philohela minor) caught in Massachusetts in the summer of 1960 and kept in captivity in Maryland, and of another group caught and kept in Louisiana in the winter of 1960-61. Bumblefoot, a granulomatous swelling of the foot caused by Micrococcus sp., is reported for woodcocks for the first time. Six of...

Effects of heptachlor-contaminated earthworms on woodcocks Effects of heptachlor-contaminated earthworms on woodcocks
The effects on woodcocks (Philohela minor) of eating heptachlor-contaminated earthworms were studied experimentally in a series of feeding trials in Louisiana in the winter of 1960-61. Six of 12 woodcocks fed worms which had been contaminated at an average of 2.86 ppm of heptachlor epoxide died within 35 days; 4 more had died by the fifty-third day, when the other 2 were killed for...
