NuTTALLORNis BOEEALis (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 cottony substances. It is saddled onto a 

 limb, usually a dead one, after the fashion of a Hummingbird's 

 or Gnatcateher's nest. The Wood Pewee begins laying about the 

 first of June. 



Empidonax 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 vieescens (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-
