NUTTALLORNIS BOREALIS (Swainson). Olive-sided Flycatcher. 
Rather rare migrant. 
A few migrating Olive-sided Flycatchers are present during 
late May and early June and again in early September. It is 
more often heard than seen and is to be looked for in the tops of 
tall, often dead, trees along water courses. It may be readily 
identified by its loud, wild and distinctive whistle. 
MYIOCHANES VIRENS (Linn.). Wood Pewee. 
Rather uncommon summer resident. 
The Wood Pewee arrives early in May and leaves in late Sep- 
tember. It is a woods-loving bird, and is found within the city 
only in the more secluded and heavily wooded sections, such as 
Swope Park. 
The nest is a very beautiful structure composed of fine ma- 
terials such as lint and ecottony substances. It is saddled onto a 
limb, usually a dead one, after the fashion of a Hummingbird’s 
or Gnateatcher’s nest. The Wood Pewee begins laying about the 
first of June. 
EXMPIDONAX FLAVIVENTRIS (W. M. & S. F. Baird). Yellow-bellied 
Flycatcher. 
Rather rare migrant. 
The Yellow-belly may not be as rare during migration as the 
few records seem to show, since it is a difficult bird to find. It 
frequents dense undergrowths and thickly grown-up bottom and 
bluff regions and is usually silent. It is present during the last 
half of May and early June (six records). There are no autumn 
records for this county, but a specimen was taken about thirty 
miles to the west on September 15, 1908, by Bunker (Kansas 
University Museum). 
EMPIDONAX VIRESCENS (Vieillot). Acadian Flycatcher. 
Somewhat common summer resident. 
The Acadian or Green Crested Flycatcher arrives during the 
first few days of May and is present until the middle of Sep- 
tember. 
It is never found outside of thickly wooded places. Its favor- 
ite haunts are the wooded ravines of the bluff regions and wher- 
ever creeks flow through timber. Two or three pairs nest regu- 
larly in Shilo Hollow, near Swope Park, and several are always 
to be found during summer in Hazel Dell, a secluded creek bot-
