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.
92. Icterus bullocki (Swains.) Bonap. Bullock’s Oriole.—Only two of these Orioles were taken during 1881: but in the previous summer Mr. Stephens found them not uncommon in the foot-hills of the Chiricahua Mountains.
93. Corvus corax carnivorus (Bartr.) Ridgw. American Raven.—Incidentally mentioned as common about Tucson.
94. Corvus cryptoleucus Couch. White-necked Raven.—A small proportion of the Ravens seen about Tucson were recognized as belonging to this species. Their notes differed widely from those of the common Raven, and “at times sounded somewhat like the quacking of a Duck.”
324, ♀ ad., Tucson, May 4. Length, 19.90; extent, 40.70; wing, 14.06; tail, 8.94. “Iris dark brown.”
95. Cyanocitta stelleri macrolopha (Baird) Ridgw. Long-crested Jay.—Five specimens, Chiricahua Mountains, March 24 to 26. “These Jays are common in the pines well up the mountain sides, but they are wary and difficult of approach. When pursued they fly from one tree to the lower branches of the next and jumping from limb to limb, take flight again as soon as they reach the top. If one can follow fast enough to get within range before the bird reaches the top of the tree he may obtain a shot, but it is necessary to keep behind some object while accomplishing this. They are noisy and have a variety of calls, some of which are disagreeably harsh. I think they are shyer here than in other localities where I have met with them.” One of Mr. Stephens’ specimens (No. 106) has the crest strongly tinged with blue, thus approaching var. diademata of Mexico.
96. Aphelocoma woodhousii (Baird) Ridgw. Woodhouse’s Jay.—One specimen, Galeyville. January 29, 1881.
97. Aphelocoma sordida arizonæ Ridgw. Arizona Jay.—Mr. Stephens met with this Jay in the Chiricahua and Santa Rita Mountains, and judging from the number of specimens obtained it must be rather abundant in both ranges. “They go in flocks of from five to twenty, and are generally seen in the foot-hills. They are restless, and in most localities shy, but around mills, where they congregate to feed on the grain in horse droppings, they become used to the presence of human beings and are more easily approached. Their food is chiefly broken acorns.”
A nest found May 16, in the Santa Rita Mountains, is a bulky structure composed chiefly of yellowish rootlets with some coarse dead twigs protecting its exterior and a scanty lining of fine grasses. The female was sitting on four eggs. which were on the point of hatching. The only specimen saved measures 1.13 × .82. It is pale greenish-blue, absolutely without markings, and closely resembles a Robin’s egg. “The others were similar, as were three eggs of a set taken in 1876, and two of one found in 1880.”
