180 SINGING BIRDS. 
bend, often of the smilax or green briar vine. In the Middle 
States they often raise 2 broods in the season, generally make 
choice of thorny thickets for their nest, and show much con- 
cern when it is approached, descending within a few feet of 
the intruder, looking down and hoarsely mewing and scolding 
with great earnestness. This petulant display of irritability is 
also continued when the brood are approached, though as large 
and as active as their vigilant and vociferous parents. In the 
Middle States this is a common species, but in Massachusetts 
rather rare. Its food, like the rest of the Vireos, is insects 
and various kinds of berries, for the former of which it hunts 
with great agility, attention, and industry. 
“ Eastern United States, west to the Rockies, south in winter to 
Guatemala,” 1s usually given as the habitat of this species. It has 
been seen rarely north of southern New England, and only one 
example has been taken in New Brunswick, though Mr: J. M. 
Jones considers it fairly common in portions of Nova Scotia. 
There is no authentic report of its occurrence in Ontario, but Mr. 
Mcllwraith thinks it may yet be found there. 
Note. — Mr. William Brewster has lately described the KEy 
WEsT VIREO (V. noveboracensis maynardi) as a larger bird than 
the type and of duller color, the yellow paler. 
BELL’s ViREO (Vireo bellz),a bird of much the same appearance 
and habits as the White-eyed, is found in the prairie districts of 
Illinois and Iowa. It ranges thence to the eastern base of the 
Rockies.
