WARBLERS 303 



YELLOW-THROATED WARBLER: Dendroica dominica 

 dominica (Linnaeus). 



State records. — The yellow-throated warbler is a common 

 summer resident over the greater part of the State. It has 

 been seen in the breeding season at Florence, Leighton, Sand 

 Mountain (Jackson County), Ardell, Auburn, Anniston, Au- 

 tauga ville, Woodbine, Squaw Shoals (Jefferson County), Jas- 

 per, Tuscaloosa, Natural Bridge, Seale, Coosada, and Castle- 

 berry. On Sand Mountain, near Carpenter, it was fairly com- 

 mon late in June and at Squaw Shoals it was the commonest 

 warbler on the pine-covered hills. It was numerous also along 

 the route from Jasper to Ardell, April 30 to May 5, 1914. 



Migrants from the south appear about the middle of March, 

 having been noted at Greensboro, March 10, (1893) ; Coosada, 

 March 13 (1878) ; Woodbine, March 16 (1908) ; Autaugaville, 

 March 17 (1913) ; Mobile, March 18 (1912) ; and Sand Moun- 

 tain (near Carpenter), April 1 (1917). 



General habits. — This warbler lives in open tracts of pine or 

 mixed timber, particularly about the borders of swamps, and 

 frequents mainly the upper branches of tall trees. It is a 

 vigorous singer, and its song, though rather simple in char- 

 acter, is loud and ringing, somewhat suggesting the song of 

 the Louisiana water-thrush. 



The nest may be placed either in pines or deciduous trees 

 and where Spanish "moss" is found, it is usually concealed in 

 a bunch of this lichen. Of 6 nests found by Dr. Avery, at 

 Greensboro, 4 were placed in sweet gums, 1 in a pine, and 1 in 

 an oak. The height of the nest above the ground varied from 

 15 to 55 feet. All were concealed in the hanging "moss." 

 The birds began to build about the first of April and eggs 

 were found in the nests on April 18 and 24. 



Food habits. — Examination of 9 stomachs of this bird from 

 Alabama showed its food to be mainly flies, beetles, ants and 

 other Hymenoptera, and spiders. 



BLACK-THROATED GREEN WARBLER: Dendroica 

 virens virens (Gmelin). 



State records. — The black-throated green warbler occurs 

 not uncommonly as a spring and fall migrant, and breeds
