this season appears to consist almost exclusively of berries, particularly 

 from the pifion and cedars, and the crops of many examined contained 

 little else save a few insects. The habit of catching insects on the 

 wing, after the manner of the flycatchers, which is attributed to this 

 bird, appears to be not a common one, as, of hundreds I have seen at 

 different seasons, none were ever thus engaged, nor have I ever seen 

 them searching among the leaves for insects, like the thrushes. In 

 their usual manner of procuring food, as in their habits and motions 

 generally, they have always seemed to me nearly allied to the bluebirds. 

 Though in summer a bird of retiring and unsocial habits, and never 

 more than a single pair being found in a locality, in the fall they are to 

 a considerable extent gregarious, associating usually in small companies 

 of from five to ten. At the Old Crater, forty miles south of Zuni, X. 

 Mex., they had congregated in very large numbers about a spring of 

 fresh water, the only supply for many miles around, and hundreds were 

 to be seen sitting on the bare volcanic rocks, apparently too timid to 

 venture down and slake their thirst while we were camped near by. 

 Their song is occasionally heard even in November and December, and 

 is very sweet, but not so full and varied as during the vernal season. 



LANIID^E (the Shrikes). 



48. Collurio ludovioiamis (L.), var. ex sub itor aides, S\v. White-ruinped 

 Shrike. 



A single individual seen at Wingate, N. Mex., in July, and a speci- 

 men obtained by Dr. Newberry at Fort Bowie, Southeastern Arizona, 

 were the only two occasions when this species was met with. Dr. Coues 

 mentions this shrike as rare also at Fort Whipple. 



TANAGEID^E (the Tanagers). 



49. Pyranga ludomciana, (Wils.) Louisiana Tanager. 



Very common at Apache, and met with frequently at various points 

 to the southward. Seen at the Gila River October 16, but at this time 

 nearly all had gone farther south. Frequents at this season the decid- 

 uous trees. 



Iris brown; bill horn-color; feet and legs bluish.
