98 EXPLORATIONS AND SURVEYS WEST OF IOOTH MERIDIAN. 



(the Dippers). 



6. C Indus mexicamiS) Sw. Water- Ouzel. 



Found among the rapids of the streams in the White Mountains, Ari- 

 zona, where, however, it did not appear to be numerous. A pair of 

 these interesting birds were seen on a small isolated pond in the high 

 pine-woods, where they seemed as perfectly at home as in their custom- 

 ary haunts on the most turbulent streams. Also met with on a mount- 

 ain-stream near Tulerosa, N. Mex. 



SAXICOLIDJI; (the Saxicolas). 



7. Sialia mexicana, Sw. Western Bluebird. 



This species was not observed till July 23 at Inscription Bock. This 

 appeared to be a favorite locality, and large numbers of both old and 

 young were congregated together in the piiion and cedar trees. Their 

 habits at this season do not differ notably from the other species. From 

 here southward they were frequently seen, commonly among the pines. 

 At Apache in August I found them in large flocks in the pine-woods, 

 and accompanied by flocks of warblers, nuthatches, and titmice, to 

 which they seemed to act as leaders, the whole flock following their 

 flight from tree to tree. 



8. Sialia arctica, Sw. Kooky-Mountain Bluebird. 



On leaving the mountainous region of Southern Colorado, this species 

 was apparently left behind, nor did I again see it till the middle of 

 [November, when I found very large flocks in the neighborhood of a 

 spring at the salt lake south of Zuni, N. Mex. They doubtless winter 

 here. 



(the Sylvias). 



9. Reyulus calendula (L.) Ruby-crowned Wren. 



Common in the White Mountains of Arizona in August, where doubt- 

 less it also breeds. Also seen at Camp Grant September 24, and com- 

 mon on the Gila Elver, among the cotton woods, October 19.
