852 ZOOLOGY— BIRDS. 



to a place in our fauna being- the capturo of a single specimen by Dr. 

 Coues at Fort Whipple. In 1873, I obtained a pair of old birds, which 

 were accompanied by several young, in the White Mountains, near Camp 

 Apache, and, not meeting with it elsewhere, supposed it to be rare. Such, 

 however, proves not to be the case, as the past season it was found to be one 

 of the most numerous and characteristic of the flycatcher tribe, being seen 

 everywhere in the mountainous districts from Camp Apache to the border 

 line. In general appearance, as well as habits, it is quite similar to the 

 Olive-sided Flycatcher, and shows the same proclivities for inhabiting' the 

 pineries, often on the edge of an opening, or where the country is diversified 

 and cut up by rocky ravines, and the pines are interspersed with oak woods. 

 In such places, the species is sure to be present, and may be seen circling 

 about the high pine stubs, or descending to the lower trees, as the oaks, and 

 launching itself out from the branches in vigorous pursuit of flies and beetles, 

 which it hunts with the greatest energy and perseverance. The notes are 

 loud and very forcibly given, possessing the same character as the call of the 

 Olive-sided Flycatcher, but are readily distinguishable. They resemble the 

 syllables pe, tvee, ee, great emphasis being- laid on the middle syllable, while 

 the last is quite prolonged and in a slightly raised key. Each pair appar- 

 ently takes possession of a large area, and allows no intrusion of their kind 

 within the limits. Having spent a few moments in one spot, the bird makes 

 a hurried dash, and in a few moments its voice can be just distinguished, as 

 it is sent back from afar in answer to the mate near by. A short interval 

 elapsing, it will suddenly re-appear from among the trees, and, with an exult- 

 ant whistle, settle firmly down on some percliing place, giving short, nervous 

 jerks of its long tail, and turning its head quickly here and there, every 

 motion betraying the nervous activity of its nature. These sudden erratic 

 flights from point to point are quite characteristic of the bird. By the 

 middle of July I found the young well fledged and quite numerous. Thus 

 the eggs are probably deposited in the first part of June. By the latter part 

 of September, many individuals had passed to the southward ; but, at Mount 

 Graham, at this time the species was still present. I noticed them on several 

 occasions (in the outskirts of the flocks of Warblers and Nuthatches, which 

 were moving slowly onward. They appeared to be migrating in their
