A common species of the temperate parts is the green heron (A. virescens), whose flesh is much esteemed. Other important species are the Great Blue Heron (A. herodias), the Great White or Florida Heron (A. occidentalis), the Great White Egret (A. egretta), and the Little White Egret (A. candidissima).
The Peacock Heron (A. helias) of South America, a small heron of exquisitely graceful shape and mien, with plumage variegated with colored spots and bars, is a favorite pet bird of the Brazilians.
Ibis (Ibidoideæ).—These birds are related to the spoonbills, and, more remotely, to the storks and herons. The bill is long, slender, curved, thick at the base, the point rather obtuse, the upper mandible deeply grooved throughout its length. The face and generally the greater part of the head, and sometimes even the neck, are destitute of feathers, at least in adult birds. The plumage is mainly white, with black feathers and plumes on the wings. The neck is long. The legs are rather long, naked above the joint, with three partially united toes in front, and one behind; the wings are moderately long; the tail is very short.
The Sacred or Egyptian Ibis, is an African bird, two feet six inches in length, although the body is little larger than that of a common fowl. The ancient Egyptians worshiped it as the emblem of purity, and used to embalm it.
The Glossy Ibis is a smaller species, also African, but migrating northward into continental Europe, and occasionally seen in Britain. It is also a North American bird. Its habits resemble those of the Sacred Ibis. Its color is black, varied with reddish brown, and exhibiting fine purple and green reflections. It has no loose pendent feathers.
The White Ibis, a species with pure white plumage, once abounded on the coasts of Florida, but has been killed off by feather hunters, so that it is rare except in the remote tropics.
The Scarlet Ibis is a tropical American species, remarkable for its brilliant plumage, which is scarlet, with a few patches of glossy black.
The Straw-necked Ibis is a large Australian bird of fine plumage, remarkable for stiff, naked, yellow feather-shafts on the neck and throat.
Plovers.—Wading shore birds sometimes also known as Sandpipers. Their bills are long for probing in the mud. The wings are long and pointed. The most peculiar species lives in New Zealand: its bill is sharply bent either to the right or left, near the end, enabling it to secure food from beneath stones.
North America has a number of species of plovers, such as the Kildeer Plover, abundant on the great western prairies, and not unfrequent in the Atlantic states. It utters, when approached by man, a querulous or plaintive cry.
