2A. Brewster o/i a Collecfion of Arizona Birds. [January 



had "innumerable eggs of some parasite between tbe muscle and 

 skin on the upper side of the wings." 



129. Centurus uropygialis i^a/r^/. Gila Woodpecker. — 

 One of the four specimens obtained during the past season is 

 accompanied bj the following notes. "Nine miles east of Tomb- 

 stone, April 8. This point is the furthest east that I have seen 

 this Woodpecker. I did not find it on the upper Gila. The 

 present specimen was among oaks and walnuts which were spar- 

 ingly distributed along an arrova. They usually frequent mes- 

 quites or giant cactuses, but the latter ai^e wanting here and the 

 mesquite is only a low shrub." The remaining three skins were 

 taken June i and 3, at Camp Lowell. 



Juv., first plu7nage. 5 (No. 477, Camp LowelL June 2). Crown with 

 faint transverse vermiculations of dull brown. The white of the back 

 and wings tinged with smokj'-brown. Abdoiiien reddisli-saffron. Other- 

 wise like adult of the same sex. 



130. Melanerpes formicivorus bairdi Ridgw. Califor- 

 NiAN Woodpecker. — Found only among the Chiricahua Moun- 

 tains where a few specimens were taken about the middle of March. 

 "In Arizona and New Mexico I have never seen acorns buried 

 in the bark of trees by this bird, as is its common practice in 

 California. Otherwise there is little difference in their habits in 

 the two regions." 



One of the Arizona examples — a female — has nearly the whole of 

 the black pectoral crescent streaked with white, thus showing an approach 

 to certain more southern races. 



131. Colaptes auratus niexicanus i^Siv.') Ridgw. Red- 

 shafted Flicker. 



115, (J ad., Chiricahua Mountains. March 26. Length, 12.90; extent, 

 20.90. "Iris dark brown. Stomach contained ants. Common- here but 

 invariably shy." This specimen has a few red feathers on the nape. 



133. Colaptes chrysoides {Malh.) Baird. Malherbe's 

 Flicker. — Mr. Stephens regards the distribution of this species 

 in Arizona as coextensive with that of the giant cactus, for he 

 has never seen it excepting where this singular plant gi'ows. In 

 coming from California by the Mohave route, in 1880, the first 

 cactuses w^ere met with on the Big Sandy River, a tributary of 

 the Bill Williams River, and C. chryso'ides was there observed 

 for the first time. During the past season the birds were found 

 in moderate numbers both at Tucson and Camp Lowell. Their 

 notes were indistinguishable from those of C. mexicanus., and in 

 a general wav their habits were much the same. They were
