200. (465). Empidonax virescens (Vieill.). Green-crested Fly- 

 catcher. 



The Flycatchers of the Empidonax group are rather difficult 

 to distinguish from each other, as their plumage, general habits, 

 and notes are quite similar. A peculiar choice of nesting sites is 

 generally characteristic of each species, but this varies consider- 

 ably. The Green-crested or ' 'Acadian" Fl3-catcher is more eastern 

 in its range, and is not reported by very man}- observers in Iowa. 



Ernest Irons describes the species as nesting around Council 

 Bluffs rather commonh- from June ist to 28th, frequenting dark, 

 shad\- woods and deep ravines. All nests were in bushes or small 

 trees on the side, near the bottom, of a ravine, preferably in iron- 

 wood saplings, though two were in hickories. Eggs are two to 

 four, with markings distinct in outline and not blotched, as is 

 sometimes the case with the eggs of trailli ("The Acadian Fly- 

 catcher in Pottawattamie County," Iowa Orn., ii, 4, 1896, pp. 80- 

 81). 



Charles R. Keyes reports the species as a "common summer 

 resident in the heavier woods along Cedar River in Linn count3^ 

 Several occupied nests can be found in a few hours' search during 

 last week of Maj' and first two or three weeks in June. Nests are 

 swung to lower, outer branches of hard maples, ironwoods, pig- 

 hickory, and whiteoaks." In Winnebago count}- it is rare. June 

 16, 1896, I took a nest with two eggs, found June 14, in a small 

 bush, three feet from the ground, near a winding woodland road; 

 birds ver}' sh}-; one shot. 



The Green-crested Fh'catcher was also reported as a common 

 summer resident in Blackhawk (Salisbury); "infrequent" (Peck); 

 Lee (Praeger, Currier): Poweshiek (Kelsey, Jones); Warren (Jeff-
