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. Cabanis. 
Head slightly crested. Bill much depressed, very broad at base. Wings pointed, 
much longer than the emarginate tail, reaching beyond its middle. Feet very small. 
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
