79. Calamospiza bicolor, (Towns.) Lark-Bun ting ; White- winged Black- 

 bird. 



A few in the worn breeding-plumage were seen in the neighborhood 

 of Zuni, 1ST. Mex., in July. Leaving here, the species was not again met 

 with till October, when they were found in large flocks in the San Pedro 

 and Gila Valleys, Arizona. They feed almost entirely at this season upon 

 the seeds of various grasses, and, when engaged in searching for these, 

 show little of the shyness attributed to them at other periods of the 

 year. By the middle of October, the males have assumed the plumage 

 of the females, and are indistinguishable from them and the young, ex- 

 cept that the streakiugs underneath are heavier and blacker, particu- 

 larly about the throat, and there is also much black on the wings. 



80. Euspiza americana, (Gm.) Black-throated Bunting. 



A specimen taken near San Pedro, Ariz., September 3. This was ap- 

 parently a mere straggler, as the species was nowhere else met with. 



81. Hedymeles melanocephalus, (Sw.) Black-headed Grossbeak. 



Rather numerous in the vicinity of Wingate, K Mex., where it breeds. 

 Common also at Apache, keeping in the tall cottonwoods and thickets 

 of the streams.
