BLACK-CAPPED VIREO. 
630. Vireo atricapillus. 4% inches. 
Male, with crown and sides of head glossy black, 
lores and eye-ring white; female, duller colored. 
This strange and comparatively rare Vireo frequents 
brushwood on the prairies of Kansas, Indian Territory 
and central and western Texas. Their habits in all 
respects resemble those of the more common Vireos or 
Greenlets as they are otherwise called. 
Notes.—Similar to those of the White-eyed Vireo. 
Nest.—Suspended as usual from forked branches at 
low elevations; made of fibres and bark strips closely 
woven together with spider webs. The four eggs are 
pure white, unmarked (.70 x .52). 
Range.—Breeds from central and western Texas 
north to southern Kansas; winters in Mexico.
