The Fly-catchers (Muscicapidæ) are a family of insectivorous birds, many of which are British, comprehending, according to Temminck, the Todies (Todus), distinguished by long, broad, and very flat bills, contracting suddenly at the tip. Characteristics:—Tail short, slender, and rounded; legs long and weak; toes short, the outer one more or less united to the middle one. T. viridis, the only species, according to Temminck, has a bright green plumage above, whitish beneath; a scarlet throat; sides rose colour; and the tail-coverts yellow. It is a native of South America and the Antilles; and Sir Hans Sloane, under the name of "Green Humming-bird," describes it as "one of the most beautiful small birds he ever saw." Mr. Browne states that it is a familiar little bird, and will often let a man come within a few feet to admire it before becoming alarmed. "It keeps much about the houses in country parts," he adds, "flies slow, and probably may be easily tamed."
It lives almost entirely on the ground, feeding on insects, which it catches in the evening. It builds its nest in the crevices on river banks, or in the soft rocks, in which it hollows out a dwelling by means of its bill and feet.
The King-fishers (Alcedo), the Martin-fishers of some authors, form a highly interesting group, of which Alcedo ispida (Linn.) is the only known species indigenous to Britain. M. Vigors finds an intimate resemblance between them and the Todies. The King-fishers are very singular birds. Their bill is strong, straight, and angular, being of immense length compared with their size; the tip of both mandibles acute; the commissure perfectly straight; the head strong and elongated; wings and tail of moderate size; tarsi short, and placed far back ([Fig. 201]). The King-fisher (A. ispida) has behind each eye a patch of light orange brown, succeeded by a white one; from each corner of the mandible proceeds a line of rich blue, tinged with green; the crown of the head is deep olive green; the feathers are tipped with a verdigris shade; chin and throat with yellowish white; breast, belly, and vent with orange brown; tail a bluish green; shafts of the feathers black; and the legs a pale brick red. This beautiful bird is as interesting in manners as in appearance. Living on the banks of rivers, they feed almost exclusively on fish. The King-fisher watches patiently from a fixed station, generally a naked twig overhanging the water, or a stone projecting above the surface, for its prey: in this position it will sometimes wait for hours, absolutely immovable. When the fish comes within reach, with great rapidity it pounces upon it, seizing it in its powerful mandibles, and after destroying it by compression, or by knocking it against a stone or the trunk of a tree, it swallows it head foremost. When fish is scarce it feeds also upon aquatic insects, which it seizes on the wing. Its aërial movements are rapid and direct, but weakly maintained, being performed by a series of quick, jerking beats of the wings, generally close to the surface: the action of the wings is so rapid as to be scarcely perceptible. The short tarsi render the King-fisher a bad walker.

The King-fisher is a solitary bird, living generally in secluded places, and is rarely seen even with birds of its own species, except in the pairing season. Like the Todies, they build their nests in the steep banks of rivers, either in the natural crevices, or in holes hollowed out by water rats; and these dwelling-places are generally disfigured by the fragments of their repast. Father and mother sit alternately, and when the young are hatched they feed them with the produce of their fishing. The bird has a shrill and piercing note, which it utters on the wing. Their flesh is very disagreeable.
The King-fisher is the Halcyon of the ancients, who attributed to it after death the power of indicating the winds. The seven days before and the seven days after the winter solstice were the Halcyon days, during which the bird was supposed to build its nest, and the sea remained perfectly calm. To its dead body the attributes of turning aside thunder-bolts, of giving beauty, peace and plenty, and other absurdities were ascribed. Even now, in some remote provinces of France, the dead birds are invested with the power of preserving woollen stuffs from the attack of the moth; hence they are called Moth Birds by drapers and shopkeepers. They are inhabitants of almost every region of the globe, and comprehend a great number of species, spread over Asia, Africa, and America.[32] Europe possesses one species not larger than a Sparrow, and which is remarkable for the rich colouring of its feathers. What, indeed, can surpass the brilliancy of the King-fisher as it suddenly darts along some murmuring brook, tracing a thread of azure and emerald? Some authors separate the King-fishers, properly so called, or riverside birds, from the Bee-eaters and other Fissirostral birds, which, while they resemble each other in many physical characteristics, differ essentially in their habits; in short, while the one haunts the river, feeds upon its inhabitants, and nests upon its margin, the other keeps to the woods and forests, feeds upon insects, and builds in holes in trees.
The Ceyx Meninting of Lesson (Alcedo Biru of Horsfield) very closely resembles the King-fisher of Europe in its habits; it darts in short, rapid flight along the surface of lakes and rivulets, emitting shrill, discordant sounds; it perches on trees on the river banks, and feeds on small fishes and aquatic insects. The tarsus is smooth, the inner toe suppressed; in other respects its habits are those of the King-fisher.
