Prominent among a great variety of song-birds and insectivorous birds are the robin, blue bird, cat bird, sparrows, meadow-lark, bobolink, thrushes, chickadee, wrens, brown thrasher, gold finch, cedar wax-wing, flycatchers, nuthatches, flicker (golden-winged woodpecker), downy and hairy woodpeckers, rose-breasted grosbeak, Baltimore oriole, barnswallow, chimney swift, purple martin, purple finch (linnet), vireos and several species of warblers.
Each group has its distinct harrier-eagle, red-cheeked paroquet, oriole, sunbird and bulbul.
It has few distinctive species, but within its borders the southern mole and cotton-tail rabbit of the South meet the northern star-nosed and Brewers moles and the varying hare of the North, and the southern bobwhite, Baltimore oriole, bluebird, catbird, chewink, thrasher and wood thrush are neighbors of the bobolink, solitary vireo and the hermit and Wilson s thrushes.
Among its characteristic mammals and birds are the sage cotton-tail, black-tailed jack-rabbit, Idaho rabbit, Oregon, Utah and Townsends ground squirrels, sage chipmunk, fivetoed kangaroo rats, pocket mice, grasshopper mice, burrowing owl, Brewers sparrow, Nevada sage sparrow, lazuli finch, sage thrasher, Nuttall s poor-will, Bullocks oriole and rough-winged swallow.

Songbirds are plentiful, especially in wooded regions, and include the American robin, oriole, thrushes, the cat-bird and various sparrows; while the English sparrow, introduced years ago, has multiplied excessively and become a nuisance in the towns.
The general style of coloration of orioles is gaudy yellow and black, rendering them invisible in sunlit foliage, and quite different from the more sombre hues of the friar-birds; but in the islands of Bourou, Timor and Ceram the orioles have not only assumed the tints of friar-birds in general, but in each of the islands named a species of oriole has acquired the little peculiarities in colour of plumage possessed by the friar-bird of the same locality.
Several birds of gorgeous plumage come north into Egypt in the spring, among others the golden oriole, the sun-bird, the roller and the blue-cheeked bee-eater.
Oriole, the yellow-headed blackbird and McCown's longspur are characteristic of the open lowlands.
Its animal life is in the main distinguished in species only from that of the Upper Sonoran belt, including among birds, the desert sparrow, desert thrasher, mocking-bird, hooded oriole; and among mammals small nocturnal species of kangaroo rats, pocket mice, mice and bats.
Of song birds the favourites are the robin, thrushes, bobolink, oriole, chickadee, meadow-lark, cat-bird, bluebird, wrens and warblers.
The blue-bird with his azure plumes, the thrush clad all in brown, the robin jerking his spasmodic throat, the oriole drifting like a flake of fire, the jolly bobolink and his happy mate, the mocking-bird imitating the notes of all, the red-bird with his one sweet trill, and the busy little wren, are all making the trees in our front yard ring with their glad song.
