Reward banding to determine reporting rate of recovered mourning dove bands Reward banding to determine reporting rate of recovered mourning dove bands

Reward bands placed on the other leg of certain regularly banded immature mourning doves (Zenaidura macroura) were used to develop information on reporting rates of recovered dove bands. Reports from 15 widely separated sections of the United States showed considerable variation in recovery rate of doves both with and without reward bands. The overall percentages of banded doves that...

Blood parasites in North American waterfowl Blood parasites in North American waterfowl

One thing seems to stand out in the overall knowledge we have of the blood parasites of waterfowl, as previously noted by Herman and Wehr, (1954): the greatest potential of losses is in the younger age groups, usually those birds 5-10 weeks old. In Leucocytozoon infections, death occurs as early as the first or second week of the bird's life. As a conclusion to this presentation, I wish...

Chlorinated hydrocarbons and eggshell changes in raptorial and fish-eating birds Chlorinated hydrocarbons and eggshell changes in raptorial and fish-eating birds

Catastrophic declines of three raptorial species in the United States have been accompanied by decreases in eggshell thickness that began in 1947, have amounted to 19 percent or more, and were identical to phenomena reported in Britain. In 1967, shell thickness in herring gull eggs from five states decreased with increases in chlorinated hydrocarbon residues.

Relative toxicity of lead and five proposed substitute shot types to pen-reared mallards Relative toxicity of lead and five proposed substitute shot types to pen-reared mallards

A 30-day toxicity test was made to determine the relative toxicity of lead, a tin-lead alloy, zinc, nickel, teflon-coated steel, and tin, all in shot form, to pen-reared mallard drakes. All of the 15 ducks dosed with lead died. Twenty-seven percent of 15 dosed with alloy, and 20 percent of 15 dosed with zinc also died. Ten of the remaining zinc-dosed ducks showed signs of distress...
