Bachman's sparrow in Maryland Bachman's sparrow in Maryland

The Bachman's Sparrow (Aimophila aestivalis bachmani) is known to be quite rare and irregular in distribution in the northern part of its range. Because of this the northern limits of its range have been rather ill-defined. According to the A. 0. U. Check-List, Fourth Edition: 343, 1931, this bird ranges north to central Virginia in the eastern part of its range and is casual near...

On June 1, near the end of the northward flight, I found a male Hooded Warbler singing in shrubby undergrowth on a wooded coulee slope on the Des Lacs National Wildlife Refuge, about two miles south of Kenmare. The bird was observed at close...

Since considerable time was spent in traversing certain sections of the forest in search of Ruffed...

Germinated seed versus ungerminated seed in diet of adult bobwhite quail Germinated seed versus ungerminated seed in diet of adult bobwhite quail

In connection with studies being conducted on the biological value of various feedstuffs, both wild and domestic, in the diet of captivity-reared adult Bobwhite quail, two tests were run in 1940 to determine if quail preferred germinated seed to ungerminated seed, and if germination might enhance the feeding value of seed in a maintenance diet.

Age determination in juvenal bobwhite quail Age determination in juvenal bobwhite quail

Following methods described by Louis Bureau (1911, 1913) in France, tabulations were made (1) of the ages at which captivity-reared bob-white quail (Colinus virginianus) dropped their juvenal remiges, and (2) the rates at which post-juvenal replacement primaries grew. These were arranged so as to permit the determination of age in healthy birds from one to five months of age. The degree...
