BIKDS. 27 



We found this little bird quite abundant along Bill Williams' Fork, in the month of Feb- 

 ruary. In its habits it very closely resembles the Psaltriparus 'plumbeus.

This little bird was found in the thick bushes along Pueblo creek. When noticed it was 

 ever in motion, hopping from twig to twig, searching for its food. We found it also among the 

 pines of the Aztec mountains.

First described from these specimens. 



We found this little bird first along the Little Colorado river, among the scattered bushes 

 in large flocks. They passed rapidly from place to place, uttering their short, quick notes. 

 We found them again along the head waters of Bill Williams' Fork, inhabiting the tops of the 

 Cottonwood trees. Attracted by their notes, they could only be seen by a very careful search. 

 A singular fact in connexion with them is, that those along the Little Colorado all had black eyes, 

 while the eyes of those found on the Fork were yellow. No other possible difference could be 

 discovered. Had they been found together, or even near each other, it might be a fair conclu- 

 ion to consider them of different sexes, merely ; but they were separated by a distance of 

 several hundred miles.

We found this bird throughout Texas and New Mexico, living, for the part, in naked and 

 desert districts, often far from water. They were never seen except in flocks. We were almost 

 sure to find them about the settlements of the prairie dog, {Cynomys ludovicianus.) When 

 on the wing they whirled around from time to time near the earth, keeping close together, and 

 descending suddenly when about to alight. They accompanied their flight with a low chirping 

 note, and sometimes kept this up while running on the ground. We never observed them 

 perched on a bush or tree.

This interesting bird we found inhabiting various points between the Eio Grande and the 

 Great Colorado. We found them very abundant along Pueblo creek ; not only in the low
