Toxicity of DDT to Japanese quail as influenced by body weight, breeding condition, and sex Toxicity of DDT to Japanese quail as influenced by body weight, breeding condition, and sex

Controlled experiments were utilized to simulate the stresses on wild birds of breeding condition and of weight loss due to migration. Light conditions in the laboratory were manipulated to produce Japanese quail (Coturnix coturnix japonica) in breeding condition and not in breeding condition. Within each of these groups, some birds were partially starved before dosage and some were...

Active anting in the Puerto Rican tanager Active anting in the Puerto Rican tanager

Anting, a bird’s intentional exposure of its body surface to chemical substances secreted by ants or other agents, has been recorded in over 20 species of birds of 40 families, mostly within the order Passeriformes. Our observations of anting in the Puerto Rico tanager (Neospingus speculiferus) extend the phenomenon to a new genus and the 14th species of the Thraupidae.

Establishing hunting regulations and allowable harvest of mallards in the United States Establishing hunting regulations and allowable harvest of mallards in the United States

As a major part of establishing hunting regulations each year in the United States, data for the mallard (Anas platyrhynchos) are examined extensively to estimate the effect of various harvest strategies on the breeding population the following spring. This requires estimates of the breeding-population level and of the production, harvest, and mortality rates. Predictions made at the...

Effect of restrictive hunting regulations on canvasbacks and redhead harvest rates and survival Effect of restrictive hunting regulations on canvasbacks and redhead harvest rates and survival

Because of low population levels, there were especially restrictive hunting regulations between 1958-1965, including complete closures during the 1960-1963 seasons, for canvasback (Aythya valimeria) and redhead (A. americana) ducks. Banding data from 1952 through 1965 indicated that restrictive regulations reduced both harvest and annual mortality rates. During the period with very...

Originally described as a disease of domestic ducks in the Netherlands, DVE has since been reported from India and Belgium. it is also believed to have occurred in...
