British Birds in Their Haunts

by C. A. Johns

THE COMMON CORMORANT
PHALACRÓCORAX CARBO

Tail of fourteen feathers. Winter—head, neck, and all the under parts, black, with green reflections; close to the base of the bill a broad white gorget; on the neck a few faint whitish lines; feathers of the back and wings bronze-colour bordered with black; primaries and tail black; beak dusky; orbits greenish yellow; irides green; feet black. Summer—feathers of the head elongated, forming a crest; on the head and neck numerous long silky white feathers; on the thighs a patch of pure white. Young birds brown and grey, the gorget greyish white. Length three feet. Eggs greenish white, chalky.

Phalacrocorax, the modern systematic name of the genus Cormorant, is given by Willughby as a synonym of the Coot, and with much propriety, for translated into English it means 'Bald Crow'. Applied to the Cormorant, it must be considered as descriptive of the semblance of baldness produced by the white feathers of the head during the breeding season. The Cormorant Willughby describes under the name of Corvus aquaticus, or Water Raven. The English name,'Corvorant', is clearly Corvus vorans, a voracious Raven; and 'Cormorant' perhaps a corruption of Corvus marinus, Sea Raven.

sea-side visitors are pretty sure of seeing more than one specimen of this bird, if they care to look for them, for the Cormorant frequents all parts of the coast as well as lakes and rivers, and does not leave us at any period of the year. Often we may see two or three of these birds flying along together at a slight distance above the surface of the sea, distinguished by their black hue, long outstretched neck, and rapid waving of the wings. They fly swiftly in a straight line, and seem to be kept from dipping into the water by making ahead at full speed. There is no buoyancy in their flight, no floating in the air, or soaring; their sole motive for using their narrow but muscular wings is clearly that they may repair to or from some favourite spot with greater speed than they can attain by swimming or diving. Occasionally, while engaged in a boating expedition, we may encounter a party of three or four occupied in fishing. They are shy, and will not allow a near approach, but even at a distance they may be distinguished by their large size, sooty hue, long necks, and hooked beaks. They sit low in the water, often dipping their heads below the surface, and in this posture advancing, in order that their search for food may not be impeded by the ripple of the water. A sheltered bay in which shoals of small fish abound is a choice resort, and here they make no long continuous stay in the swimming attitude, but suddenly and frequently dive, remaining below a longer or shorter time, according to the depth which they have to descend in order to secure their prey, but when successful, occupying but a very brief space of time in swallowing it. Not unfrequently they may be discerned from the shore similarly occupied, floating or diving in the midst of the very breakers. Sometimes, but rarely, one settles on a rail or stump of a tree close to the water in a tidal river. The capture of fish is still its object, and it is quite as expert in securing its prey from such a station as when roving at large on the open sea.

All along our coast there is at various intervals a rock popularly distinguished in the neighbourhood by the name of 'Shag rock'. Such a rock is generally low, isolated, and situated at a safe distance from land; or, if near the shore, is close to the base of a steep cliff. Hither the Cormorants, when their hunger is appeased, repair for the threefold purpose of resting, digesting their food, and drying their wings. The process of digestion is soon completed, but the time consumed in drying their thoroughly drenched wings depends on the amount of sunshine and air moving. Of these, whatever they may be, they know how to avail themselves to perfection. They station themselves on the highest ridge of the rock, wide apart, and in a row, so as not to screen one another, raise their bodies to their full height, and spread their wings to their utmost extent. No laundress is more cunning in the exercise of her vocation. Indeed, they can hardly fail to recall the idea of so many pairs of black trousers hung out to be aired.

Cormorants do not confine their fishing expeditions to the sea, but frequently ascend tidal rivers, and follow the course of streams which communicate with fish-ponds and lakes, where they commit great havoc; for the quantity of fish which they devour at a meal is very great. Pliny has observed that the Cormorant sometimes perches on trees; and the truth of this remark has been confirmed by many subsequent writers. They have been even known to build their nest in a tree, but this is a rare occurrence.[29] They generally select exposed rocks, where they collect a large quantity of sticks and rubbish, and lay three or four eggs in a depression on the summit.

Most people are familiar with a representation of a fishery with the help of Cormorants conducted by the Chinese; but it is not so generally known that a similar method once was practised in England. Willughby quoting Faber's Annotations on the Animals of Recchus, says: 'It is the custom in England to train Cormorants to catch fish. While conveying the birds to the fishing-ground the fishermen keep the heads and eyes of the birds covered to prevent them from being alarmed. When they have reached the rivers, they take off the hoods, and having first tied a leather strap loosely round the lower part of the neck, that the birds may be unable to swallow down what fishes they catch, throw them into the water. They immediately set to work and pursue the fish beneath them with marvellous rapidity. When they have caught one they rise to the surface, and, having first pinched it with their beaks, swallow it as far as the strap permits, and renew the chase until they have caught from five to six each. On being called to return to their masters' fist, they obey with alacrity, and bring up, one by one, the fish they have swallowed, injured no farther than that they are slightly crushed. The fishing being brought to an end, the birds are removed from the neighbourhood of the water, the strap is untied, and a few of the captured fish, thrown to them as their share of the booty, are dexterously caught before they touch the ground.'
