200 Brewster On a Collection of Arizona Birds. 
87 . Calamospiza bicolor (Towns.) 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 ( Gmel .) 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 phceniceus (Linn.) Vieill. Red- winged 
Blackbird. 
511, $ ad., Tucson, June 8. Length, 8.10; extent, 13.20; wing, 4.22; 
tail, 3.40. 
90. Icterus parisiorum Bonap. 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. 
Juv., first plumage ($ , No. 528, Tucson, June 14). Generally 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 have 
the adult plumage perfected. A female (No. 189, Tombstone, April 10) 
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 cucullatus Swains. 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.
