U67. BLACK-THROATED GREEN WARBLER (From Brehm.) 



Two nests of the Western Warbler were found by C. A. Allen during the season 

 of 1886, in Blue Canon, California. The first contained two eggs June 4, and was 

 left for a full set. Three days after it was found in a dilapidated condition and the 

 eggs destroyed, evidently the work of squirrels. The eggs, however, are described as 

 resembling those of the Yellow Warbler, D. (estiva, but were more heavily marked. 

 Another nest was found June 7, containing three young birds and one was found seven 

 or eight years previous also containing three young. These nests were all similarly 

 placed and well concealed in "pitch pines" from twenty-five to forty feet above- the 

 ground on thick, scraggy limbs, and very difficult to find. The cavity of the nest 

 taken June 7, 1886, measures 1.25 deep by 2.50 across; external diameter 4.50 by 2.00 

 in depth. It was composed of fibrous stalks of plants, fine dead twigs, lichens, a little 

 cotton twine, and is lined with soft inner bark and hair. Major Bendire had what he 

 believed to be a set of the eggs of this Warbler taken at Big Meadows, Oregon, on the 

 banks of the Des Chutes River near its head waters, June 12, 1882. The nest was 

 placed in the crotch of a willow overhanging the water, and the parent was shot but 

 fell into the water and was carried away. The eggs are described as being about the 

 size of those of D. vstim, and resemble the eggs of D. blackburniw, with the exception 

 of the ground-color, the green of which is not as perceptible as in the eggs of black- 

 burnicc. They have a faint grayish-green ground, two of them heavily spotted with 

 lilac and dark umber-brown.*
