Genus Xuttallornis Ridgway. 



197- (459)- Nuttallomis borealis (Swains.). Olive-sided Fly- 

 catcher. 



The Olive-sided Flycatcher is generally reported as a rather 

 rare spring and fall migrant throughout the state during the lat- 

 ter part of May and the last week of August and 6rst half of 

 September. In a few localities it appears to be more common — 

 Blackhawk (Peck); Kossuth ( Bingaman ) ; Dallas (Law, Iowa 

 Orn., i, 2, 1895, P- 20); Winnebago (Anderson). On August 28, 

 1897, shot one male; September 4, saw one; September 5, saw 

 two; September 12, 1901, saw several, at Forest City. They 

 were generally' perched upon the topmost branches of large dead 

 trees and appeared rather heavy and slow in their movements. 



Genus Contopus Cabanis. 

 Subgenus Contupus Cabanis. 



198. (461). Contopus vircns (Linn.1. Wood Pewee. 



The Wood Pewee is a common summer resident in woodlands 

 in all parts of the state from the middle of May until September. 

 Its drawling, plaintive note oi pee-a-wce may be heard at all hours 

 of the day throughout the .season. The Wood Pewee nests rather 

 late, saddling a verj' neat, lichen-covered nest upon a horizontal 

 limb, usually at some distance from the ground, and often diffi- 

 cult to distinguish from a knot on the limb. B. H. Wilson gives 

 the earliest nesting date in Scott county as June 15, 1889. I 

 found two nests containing three eggs each on June 19, 1894, i^ 

 Winnebago count}-, where the average date for complete sets is 

 about June 25.
