108 EXPLORATIONS AND SURVEYS WEST OF 100TH MERIDIAN. 



50. Pyranga, liepatica, Sw. Liver-colored Tanager. 



A single female of this little-known species was shot at Apaclie Au- 

 gust 4. In a grove of oaks on the skirts of a pine-forest, about twenty 

 miles south of Apache, I saw, in the course of an afternoon, perhaps 

 half a dozen males. They appeared to be feeding upon insects, which 

 they gleaned from among the foliage and smaller branches of the oaks. 

 They were excessively shy, so much so that I found it difficult to get 

 within gun-shot of them. They probably spend the summer in the 

 mountains, at least as far north as Apache. The species was introduced 

 into our fauna by Dr. Woodhouse, who took a single female in the San 

 Francisco Mountains, New Mexico. No other specimens have since 

 been obtained till the present time. 



51. Pyranga (estiva (L.), var. cooperi, Eidg. Cooper's Tanager. 



A beautiful adult male of this variety of the Summer-Tannager (P. 

 cestiva] was taken on the Gila Eiver, Arizona, September 16, and another 

 heard in same locality ; also noted on the San Francisco Eiver October 

 10. In each instance they were found in the tall cottonwoods, actively 

 engaged searching for insects. 



FRINGILLID./E (the Finches). 

 52. Hesperiphona vespertine,, (Coop.) Evening-Grossbeak. 



A small flock of immature birds were seen a little south of Apache 

 feeding upon savis-berries. Not seen elsewhere.
