Harris—Birds of the Kansas City Region. 3138 
prefers thick wooded creek bottoms and ravines near water. It 
nests regularly in Shilo Hollow at the edge of Swope Park and 
in the Hazel Dell neighborhood within the Park. It is most 
numerous during migration in the Missouri Valley and along 
the bluffs. 
LANIVIREO SOLITARIUS SOLITARIUS (Wilson). Blue-headed Vireo. 
Not uncommon migrant. 
The Solitary Vireo is a comparatively late visitor, arriving 
during the last few days in April or the first week in May, 
often remaining till the last of May (May 26, 1893, May 15, 
1899, May 18, 1915, and May 28, 1916, latest). It leaves for 
the south during the last few days of September. It is seen 
regularly along Brush Creek in the Country Club district, in 
the Missouri and Blue Valleys, along the bluffs, about Inde- 
pendence and in Swope Park. 
VIREO GRISEUS GRISEUS (Boddaert). White-eyed Vireo. 
Fairly common summer resident. 
The White-eyed Vireo arrives from April 26th to May 4th 
and leaves during the second and third weeks of September at 
which time it is usually in full song. 
The nesting period begins early in June. It is found in the 
rich undergrowth of timbered places near streams and near the 
edges of clearings. It breeds in such places over the entire 
county but is more numerous in the Missouri bottoms and along 
the bluff ravines and creeks. Several pairs nest regularly in and 
about Swope Park. 
VIREO BELLI BELLI Audubon. Bell’s Vireo. 
Fairly common summer resident. 
The Bell’s Vireo was made known to science by Audubon 
who met with it for the first time in the bottom lands of the 
Missouri between Fort Leavenworth and St. Joseph. The first 
specimen was shot by J. G. Bell, a member of Audubon’s party, 
on May 4, 1843. The Bell’s Vireo and the Harris’s Sparrow are 
the two birds which have been discovered in the territory cov- 
ered in this list. 
This vireo arrives during the first days of May, seldom be- 
fore the third (April 30, 1899, April 27, 1900, earliest), and 
leaves for the south shortly after the middle of September.
