The TREE ALCYONS (Halcyones) are recognisable by their long, straight, broad beak, which in some species turns slightly upwards, their short feet, moderate-sized and rounded wing, with its third quill only a trifle longer than the fourth and fifth, and a comparatively short and rounded tail.
THE RED-BREASTED TREE ALCYON.
The RED-BREASTED TREE ALCYON (Halcyon rufiventris) is black on the mantle, and reddish brown on the under side; the head, back, and sides of the throat are ash-grey; the lower part of the back, the tail, and a large spot on the wings are of a metallic green; the front of the throat is pure white, the breast dirty white, and the cheek-stripes black. When seen from beneath, the wing is of reddish brown, marked with white, and tipped with black; the under side of the tail is similarly coloured; the eye is brown, the beak and feet red. This species is eight inches and a half long; the wing measures three inches and a half, and the tail two inches and a half.
The Halcyon rufiventris is an inhabitant of Western and Central Africa, where, according to our own observations in Eastern Soudan, it principally frequents well-watered and woodland districts, in preference to the scanty growth of brushwood to be found in the vast and arid steppes. The nest usually contains three round, glossy white eggs; these are laid in October or November, and are hatched by the united care of both parents; on the male alone, however, devolves the task of rearing the nestlings.
The WOOD ALCYONS (Todiramphus) have the beak still shorter, broader, and more decidedly turned upwards than in the birds last mentioned; the wing is also somewhat larger, and its second quill almost equals the third in length. The various members of this group principally inhabit Australia and the most extensive of the neighbouring islands; whilst in India, although they are occasionally met with, the species are few and comparatively rare.
