134 EXPLORATIONS AND SURVEYS WEST OF 100TH MERIDIAN. 



ill this region, bears all over its body marks of the work of these birds, 

 large patches being dug entirely out, as though the pith or sap was 

 sought for. Its trunk, too, appears to afford a favorite nesting-site, and 

 the excavations for this purpose are often to be seen. On the San 

 Pedro, this species was found frequenting the mezquite-trees. They 

 were everywhere very shy. 



133. Melanerpes torquatus, (Wils.) Lewis's Woodpecker. 



A few only seen about Apache, where it was noticed circling about 

 the tops of the high, isolated pines. Dr. Newberry, jr., reported it as 

 quite numerous in the White Mountains, where it kept constantly among 

 the pines. 



134. Melanerpes formicivorus, (Sw.) California!! Woodpecker. 



In the neighborhood of Apache, in August, this was much the most 

 abundant of the woodpeckers. They showed extreme sociability, 

 moving about in small companies of from six to twelve, and keeping 

 constantly in the oak-groves. When not busied gleaning insects among 

 the branches, they were constantly engaged in playing, chasing each 

 other in and out among the trees, and apparently the utmost good-will 

 prevailed in their companies. 



135. Colaptes auratus (L.), var. meocicanus, Sw. Bed-shafted Woodpecker. 

 Numerous, without reference to special locality.
