72. Peucaea cassini, (Woodh.) 



Arrives about the middle of March, its sweet song attracting atten- 

 tion at once. Found in ratlier open chaparral, but usually keeping iu 

 thick bushes, where alone it permits a near approach. It usually sings 

 while hidden in some bush, and, I think,. rarely utters its notes on 

 the wing unless the female is sitting. Its nest is difficult to find ; tLree, 

 taken April 28, and May 4 and 22, 1877, respectively, were placed at tbe 

 foot of small bushes and scarcely raised from the ground. They were 

 composed of dried grasses, lined with finer ones and a few hairs, but 

 were very frail. Thirteen eggs taken from these nests are pure white, 

 and average .74 by .57. Feet and legs are peculiarly light yellowish- 

 white; bill pale horn-color, darker above; iris light hazel. — (Dresser, 

 Ibis, 1865, 489.— Sennett, B. Rio Grande, 18.) 



73. Embernagra rufivirgata, Lawr. 



A common resident, frequenting thickets and brush-fences, and per- 

 mitting a close approach. The only note I have heard, besides a chij) 

 of alarm, is a repeated chip chip chip, begun slowly, but rapidly increas- 

 iug till the notes run into each other. I have found the nests with eggs 

 at intervals from May 9 to September 7. These are placed in low 

 bushes, rarely more than three feet from the ground : the nests are 

 rather large, composed of twigs and straws, and lined with finer straws 

 and hairs; they are practically domed, the nests being placed ratber 

 obliquely, and the part above the entrance being somewhat built out. 

 The eggs are from two to four iu number : thirty-two average .88 by 

 .65, the extremes being .97 by .67 and .81 by .61 ; they are pure white. 

 Two, and probably three, broods are raised in a season. — (Sennett, B. 

 Rio Grande, 22.) 



74. Calamospiza bicolor, (Towns.) 



liither common during the winter months. — (Dresser, Ibis, 1865, 

 490.) 



75. Euspiza americana, (Gmel.) 



Common during the spring migration of 1877. — (Dresser, Ibis, 1865, 

 490. — Sennett, B. Rio Grande, 19.) 



76. *Guiraca caerulea, (Liuu.) 



A rather common summer visitor, four or five pairs having nests in 

 patches of tall weeds on the reservation. — (Dresser, Ibis, 1865, 491. — 

 Goniaphea c, Sennett, B. Rio Grande, 19.) 



77. Cyanospiza cyanea, (Liun.) 

 Not rare iu April and May. 



78. Cyanospiza versicolor, (Bonap.) 



First taken April 23, 1877. This beautiful species seems to be rather 

 abundant in this vicinity, frequenting mesquite chaparral. Its song has 

 some resemblance to that of the Indigo-bird, and is constantly uttered. 

 I did not succeed in finding any nests.
