Drought displaced movement of North American pintails into Siberia Drought displaced movement of North American pintails into Siberia
During the years 1954-70, 230 pintails (Anas acuta) banded in North America were reported from eastern Asia, primarily Siberia. Most of the birds were shot on the breeding grounds in May. The movement into eastern Asia of pintails banded in the interior of North America was directly correlated with the overflight of the southern portion of the breeding range in North America (r = +0.73**...

Effect of salt on the response of birds to sucrose Effect of salt on the response of birds to sucrose
The preference of male red-winged blackbirds for solutions of sucrose and sucrose with 0.03 M sodium chloride was tested, using a two-bottle choice test. Preliminary experiments demonstrated that the birds were indifferent to 0.03 M NaCl in water. Both control and experimental animals exhibited indifference to the solutions at the lowest concentration and aversion at the highest. The...

Pesticide residues in eggs of wild birds: Adjustment for loss of moisture and lipid Pesticide residues in eggs of wild birds: Adjustment for loss of moisture and lipid
Eggs of wild birds collected for the purpose of measuring concentrations of pesticides or other pollutants vary from nearly fresh to nearly dry so that objective comparisons cannot be made on the basis of weight of the contents at the time of collection. Residue concentrations in the nearly dry eggs can be greatly exaggerated by this artifact. Valid interpretation of residue data depends...

Bird collections in the United States and Canada Bird collections in the United States and Canada
This survey was initiated in 1966 as a project of a subcommittee of the A.O.U.'s Committee on Research, at that time chaired by Paul H. Baldwin. The subcommittee consisted of the authors and Ralph J. Raitt. In 1968 the project was separated from the Committee on Research and the temporary Committee on Collections was established, with the present authors as its members. This paper is the...

Eastward migration of blue-winged teal Eastward migration of blue-winged teal
Of 3,789 recoveries of blue-winged teal (Anas discors) banded prior to the hunting season in the prairie pothole region, 183 (4.8 percent) were recovered, due east in New England, Ontario, Quebec, and the Maritime Provinces during the subsequent hunting season. Of 19 recoveries looked at in detail, all were banded as either hatching-year (flying young) or local (flightless young) birds...

Migration patterns and wintering localities of American ospreys Migration patterns and wintering localities of American ospreys
North American ospreys (Pandion haliaetus carolinensis), banded primarily in the Middle Atlantic States and in New England, apparently migrate to their winter grounds in the West Indies and South America on a broad front. Ospreys do not return to the United States as 1-year-olds, but an estimated 28 to 55 percent return to their natal vicinity (state where hatched or an adjacent state)...
