At Mount Graham, Ariz., in September, this warbler was found in con- 

 siderable numbers, though the few taken were "procured with no little 

 difficulty, for they almost invariably were seen in the tops of the tallest 

 trees, where a glimpse might now and then be had of them as they dashed 

 out after flying insects, or flew from tree to tree in their always onward 

 migratory course. The tracts of pine woods they shunned entirely, but 

 affected the firs and spruces, and their flights from point to point were regulated 

 and made longer or shorter by the presence or absence of these trees. Their 

 movements were exceedingly rapid ; a moment spent in passing in and out 

 the interlacing branches, a few hurried sweeps at their extremities, and they 

 were off to the next adjoining tree to repeat the process again and again till 

 lost sight of in the dense woods. Their only note was the common t,sip. I 

 obtained no evidence of their breeding in Arizona, though from their habits 

 there seems to exist no reason why these mountain forests should not furnish 

 a congenial summer home. Mr. Aiken obtained two specimens in Colorado, 

 thus including tha.t Territory in the range of the species.
