PASSERES— TYRANN1DAE— CONTOPUS PEETINAX.

the actions of several pairs, I felt sure that certain thick, tall fir trees had 

 been selected as the sites of their nests, but these I was not able to detect, 

 and I do not think that the nest is finished and the eggs deposited much, if 

 any, before the latter part of June. 



We found it almost as numerous in Eastern Arizona, quite far to the 

 south, as in Colorado ; but I had supposed that it was only thus present 

 during the migrations. The past season, however, specimens were taken 

 near Camp Apache in July, which doubtless were breeding, and later, about 

 the middle of August, young and old were secured near Camp Bowie, within 

 one hundred miles of Mexico. Its replacement, therefore, in this region 

 by Contojnts %)ertinax would appear to be only partial, and the two breed in 

 the same districts.
