Green and blue are the predominating colours of its upper- and bright chestnut-red of its under-surface; but owing to structural peculiarities of the feathers of the upper-parts, the reflection of the green and blue areas changes with the direction of the light from which the bird is viewed, in the same way that the peacock's train-feathers change according as the light falls upon them.
As is the rule where both sexes are brilliantly coloured, this bird breeds in a hole, which in the present species is generally excavated in the bank of a stream, but sometimes in an old gravel-pit or chalk-pit, a mile or even more from the water. Occasionally the crumbling soil under the roots of an old tree affords sufficient shelter. No nest is made, although what is equivalent to a nest is ultimately formed from the bird's habit of ejecting the indigestible parts of its food on to the floor of the space in which the eggs are laid. In course of time this becomes a cup-shaped structure; but whether, as Professor Newton remarks, by the pleasure of the bird or the moisture of the soil, or both, is unknown. With care the nest may be removed entire, but the slightest jar reduces the whole to the collection of fish-bones and crustacean skeletons of which it was originally composed. There is a tradition, not yet extinct, to the effect that these "nests" are of great pecuniary value, and scarcely a year passes without the authorities at the British Museum being offered such a treasure, at prices varying from a few pounds to a hundred. The nest-chamber is approached by a tunnel sloping upwards, and varying from 8 inches to 3 feet in length, terminating in a chamber some 6 inches in diameter, in which the eggs are laid. These, from six to eight in number, have a pure white, shining shell, tinged with a most exquisite pink colour, which is lost when the eggs are blown.
The young seem to be reared under very unsanitary conditions, for the ejected fish-bones and other hard parts are not reserved entirely for the nest, but gradually distributed along the tunnel approaching it; later, fish brought for the young, but dropped on the way, and the fluid excreta of the parents are added, forming a dripping, fetid mass swarming with maggots. The young, on leaving the nest, are at first tenderly fed and cared for by the parents, but towards the end of the summer seem to be driven away to seek new fishing-grounds for themselves.
Of the many legends that have grown up around this bird, some are well worth repeating. Specially interesting is one related by Professor Newton on the authority of the French naturalist Rolland. This has it that the kingfisher was originally a plain grey bird, and acquired its present bright colours by flying towards the sun on its liberation from Noah's ark, when its upper-surface assumed the hue of the sky above it, and its lower plumage was scorched by the heat of the setting sun to the tint it now bears. Not a few virtues were also attributed to this bird. Its dried body would, it was believed, avert thunder-bolts, or, kept in a wardrobe, preserve from moths the woollen stuffs contained therein, whilst, hung by a thread from the ceiling of a room, it would serve like the more conventional weather-cock to point the direction of the prevailing wind.
Persecuted though it is, the kingfisher is by no means a rare bird in England, and those who will may generally see it by the banks of some slowly flowing stream or lake, or even shallow brook, sometimes even by the seashore. It feeds upon small aquatic insects and crustacea and small fishes, sometimes even, it is said, upon leeches. Perched on some bough overhanging the water, or stump or railing on the bank, it watches patiently, silent and motionless. The moment its prey comes within striking distance it plunges down upon it, disappearing for a moment beneath the surface, to appear the next with its capture in its beak. If this be a fish, it is held crosswise, and borne upwards to the station from which the plunge was made, there to be stunned by a few sharp blows, tossed into the air, dexterously caught, and swallowed head-foremost. At times, however, perhaps when hunger presses, more activity in the capture of food is displayed, the bird hovering suspended over the water, after the custom of the kestrel-hawk.
Although essentially fish-eating birds, a considerable number live far removed from water, obtaining a livelihood by the capture of insects in forest regions, whilst some appear to feed mainly on reptiles. These are known as Wood-kingfishers, to distinguish them from the Water-kingfishers, the typical member of which group has been just described.
