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.
There are many kinds of birds, notably the megapod (Megapodius nic.), the edible-nest-building swift (Collocalia nidifica), the hackled and pied pigeons (Calaenas nic. and Carpophaga bicolor), a paroquet (Palaeornis caniceps) and an oriole (Oriolus macrourus).
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.
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.
