Scattered throughout the island and especially plentiful in the Sierras, is the Cuban lizard-cuckoo, known to the natives as the arriero. He is about twenty inches in length, the long broad tail representing about three-fifths while the bill will add almost two inches. The arriero is one of the most interesting members of Cuban avifauna. His color is a pale greyish brown with a metallic flush. The throat and the anterior part of the under-surfaces are grey, washed with pale brown, while the posterior portion is a pale reddish brown. The large, broad tail feathers are tipped with white and crossed by a broad band of black. He is a veritable clown, of curious and inquiring turn of mind, and extremely amusing in his antics. Having responded to your call, he will inspect you carefully, moving his tail sidewise, or cocking it up like a wren. He may slink away like a shadow, or he may spread his wings and tumble over himself, chattering as if he had discovered the most amusing thing in the world, and was bubbling over with mirth. One of the most strikingly colored birds in Cuba is the trogon. The top of his head is metallic purple, the entire back metallic green, while the under parts are pale grey, a little lighter at the throat. The posterior and under tail coverts are scarlet, while the primaries of the wing, and part of the secondaries, are marked with white bars. The outer tail feathers also are tipped with broad bands of white, the combination giving to the bird a strikingly brilliant appearance. The Trogon is inclined to conceal his beauty in thickets, and rarely displays himself in the open. His call suggests that of the northern cuckoos. Water birds are very plentiful, especially in the shallow lagoons that for hundreds of miles separate the mainland from the outlying islands. The largest and most striking of these is probably the flamingo, great flocks of which may be seen in the early morning, spreading out like a line of red-coated soldiers along the sand spits, or restingas, that frequently reach out from shore a mile or more, into the shallow salt waters. The flamingos are very shy, seldom permitting man to approach within 200 yards. Another beautiful water bird is the Sevilla that reaches, with maturity, about the size of the Muscovy cock. Until nearly a year old this beautiful inhabitant of the lagoons is snow white, after which his color changes to a bright carmine red. In the unfrequented lagoons he is still very plentiful. In the same waters are found many varieties of the heron family, including the much sought for little white heron, with its beautiful plumage, from which the aigrettes so popular among women as ornaments are obtained.
