87. Calamospiza bicolor (Towns.) Bonap. Lark Bunting.—Several large flocks were seen April 13, in the neighborhood 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.) Coues. 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. Agelæus phœniceus (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 occasionally 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.”
