The parrots may be called the monkeys among the birds; for, like the monkeys, they seek their food while climbing, but are awkward and clumsy when on the ground. Their imitative qualities and docility, their obstinacy and slyness, and their disagreeable voice and gregarious habits, all serve to remind us of the monkeys.
Toucan (Rhamphastus toco), a bird of the American tropics, is related to the woodpeckers and parrots. It belongs to the most curious of the animal forms, as its immense beak is treble the length of its head. The tongue is horny, slender, and brush-like; the considerable tail is hinged next the pelvis, so that it can be thrown over the back when resting and where the bill lies also during sleep. Toucans are omnivorous, but prefer fruit, live in flocks in forests, and nest in hollow trees. There are over fifty species, in size from that of a robin to a crow, and colored from green to black, variegated with red, yellow and white. The largest is two feet long, with bill eight inches long and three inches high.
Woodpecker (Picidæ) includes any of three hundred birds which have climbing feet, stiff tail feathers and which bore into trees for grubs on which they feed, though some of them are fond of fruit and other vegetable food. Most of the species have barbed and pointed tongues with which they spear the larvæ, but in some the tongue is smeared with a sticky substance, secreted by glands in the throat. There are no woodpeckers in Australia or Madagascar, but they occur in all other parts of the world. The prevailing color of the plumage is green—dark olive on the upper, pale green on the under parts; the crown and back of the head are bright crimson.
Of the numerous American species the flickers, the South American ground-flickers, which live chiefly on termites, and the great ivory-billed woodpecker may be specially noted. The last-named species, which inhabits the dense forests of the southern States, is one of the handsomest of the group, and was once called the prince of woodpeckers.
The woodpeckers lead a solitary life. Their presence is generally known by the noise they make while pecking; holding fast to a tree, they hack at it with their long, sharp beaks, so that splinters and chips fly in all directions. The woodpecker excavates a hole in the rotten tree, in order therein to build its nest.
THE SINGING BIRDS
Not all the birds belonging to this class are veritable songsters; but nearly all of them have in the throat an organ of song, consisting of five or six pairs of muscles, by means of which they can produce a variety of notes. They are mostly small, prettily colored birds, which chiefly inhabit the Temperate Zones, and make themselves very useful by devouring the insects, worms, and seeds of weeds in the fields, gardens, and woods. They delight us with their song; but their song is also the reason why some of them are kept in captivity.
Birds of Paradise (Paradisea apoda), though song birds of some ability, are more particularly notable for their gorgeous plumage. They are natives of New Guinea and Australia, and are very closely allied to the crow family, both in their habits and voice. The Great Bird of Paradise is the largest of the species, measuring about one and one-half feet in length; the others are comparatively small. The adult males are in beauty unsurpassed even by humming-birds. Tufts of bright feathers spring from beneath the wings, from the tail, or from the head, back, or shoulders. Trains, fans, and exquisitely delicate tress-like decorations occur abundantly, and the gracefulness of the plumage is enhanced by the brilliant color and metallic luster. The females are plain, sober-colored birds, and it is only with maturity that the males acquire that brilliancy of plumage which they exhibit to such advantage in their courtships. The true birds of paradise feed on fruits and insects, and are practically omnivorous. Their mode of life is more or less gregarious. Their song consists of a series of loud, shrill notes.
Blackbird (Turdus merula), is a member of the thrush family. The plumage of the male is quite black, and the beak yellow; the female is dark brown above, and greyish brown on the under parts, with a brown beak. It is shy, solitary, nests in March, and has two broods during the season. The nest is plastered [213] inside with mud; four or six blue eggs, speckled with black, are laid. The bird feeds mainly on insects. It is a mocking bird, but not so good a songster as the song-thrush. In confinement it can be taught.
The American Crow-blackbird or Purple Grackle is restricted to the region east of the Rockies, the Blue-headed Grackle is confined west of the Mississippi, while the Rusty Grackle pervades the whole continent.
