OLIVE-SIDED FLYCATCHER. 371 



for the nest. Mr. Mebs, an ornithologist of this city, brought me a nest 

 which he took from the beams of a freight car which had recently made 

 a trip of forty-five miles. The five eggs which it contained were per- 

 fectly fresh, and, except one, unbroken. 



The nest of the Pewee is built of clay, tempered by the bill of the 

 bird, and attached to the face of rocks, beams, or walls. It is usually 

 covered, sometimes very artistically, with moss, and lined with grass and 

 feathers. The eggs are generally five, pure white. Not unfrequently, 

 however, they are sparsely dotted with reddish-brown. They measure 

 .80 by .60. 



Genus CONTOPUS. CabaniB. 

 Head slightly crested. Bill much depressed, very broad at base. Wings pointed, 

 mnch longer than the emarginate tail, reaching beyond its middle. Feet very smalls 

 Tarsus shorter than middle toe and claw.

Rare migrant. The Olive-sided Flycatcher was first named as an Ohio 

 bird in my catalogue (1861), on the authority of Mr. R. K. Winslow, who 

 stated that it had been found at Cleveland. Mr. Dury informed me that 

 he had taken one specimen at Cincinnati, and I am almost positive that 

 I have seen one specimen here. On the other hand, Mr. Winslow is not 

 now able to recall the particulars of its capture, and it is not given by
