ZOOLOGY BIKDS. 



Arizona, and Western New Mexico, this little Titmouse is abundant and 

 quite generally distributed, though it avoids the heavy pines, among which 

 I have never seen it, seeking especially the hilly regions covered with 

 pinons and cedars, where they may be seen in fall and winter in very large 

 flocks. In such localities, they probably breed, as I found them in the worn 

 dress peculiar to this period. They are also fond of frequenting the heavy 

 brush along the streams and canon sides. This is one of the most active 

 and industrious of the family ; constantly on the move, searching here and 

 there with sharp, prying eyes for the various small insects and their larvse. 

 It is perfectly fearless, knowing no danger, and its social disposition is shown 

 in its custom of uniting in flocks often numbering fifty or one hundred 

 individuals, which, as they move along intent on their hunting forays, keep 

 up an incessant querulous chirping.
