200 Brewster on a Collection of Arizona Birds. 



87. Calamospiza bicolor ( Zbu'wj, . ) Bonap, Lark Bun- 

 ting. — Several large flocks were seen April 13, in the neighbor- 

 hood of Tombstone. Most of the males were in parti-colored 

 dress, not above one per cent having put on the black breeding- 

 plumage. The stomachs of all which were killed contained 

 "buds and seeds." 



88. Molothrus ater obscurus {G?nel.) Cones. Dwarf 

 Cowbird. 



277, $ ad., Tucson, April 25. Length. 7.30; extent. 12.40; wing, 4.02: 

 tail, 3.20. " Iris dark brown." 



417, $ ad., Santa Rita Mountains, May 20. Length, 7.10; extent. 12 10: 

 wing, 4.01 ; tail, 3.17. 



89. Agelaeus phoeniceus {Linn.) Vlelll. Red-winged 

 Blackbird. 



511, $ ad.. Tucson, June 8. Length. 8.10: extent. 13.20; wing. 4.22: 

 tail, 3.40. 



90. Icterus parisiorumiS'f; //a/. Scott's Oriole.— Although 

 this Oriole was oftenest seen among the foot-hills it occasion- 

 ally occurred on the most barren plains, where it seemed content 

 with the scanty shelter afforded by the cactus thickets. In the 

 hill country it frequented the oak belt, and was seldom observed 

 at a high elevation. During the breeding season it was seen near 

 Tucson, as well as among the Santa Rita Mountains, but no nests 

 were found in either locality. 



Jiiv., first plumage ($ . No. 528, Tucson. June 14). Generalh- like the 

 adult, but with all the wing-feathers edged and tipped with white, the wing- 

 bands yellowish, the tail tipped with yellow, the breast obscured with 

 brownish, and the yellow of the under parts paler and greener. 



Only a small proportion of the males collected by Mr. Stephens ha%e 

 the adult plumage perfected. A female (No. 189, Tombstone, April lo) 

 has a black throat-patch extending from the chin to the breast, and small, 

 sagittate black spots on the crown. 



"Iris dark brown; bill black, bluish at base below; legs dark bluish. 

 Food, insects." 



91. Icterus cucuUatus S-walns. Hooded Oriole. — 

 An uncommon .species, found only in the valleys, where it seemed 

 to prefer cottonwoods to other trees. 



The specimens taken are all adults, with the exception of a male 

 which, although evidently a bird of the previous year, differs from the 

 females only in having a black throat-patch and several concealed black 

 spots on the interscapulars. One of the females is also peculiar in having 

 many half-concealed black spots on the throat and jugulum. Some of 

 the richest-colored males have the interscapular feathers tipped with yellow.
