looked because it is familiar, since it would be as difficult to be explained as the most stupendous phænomenon in nature.

“Say, what impels, amidst surrounding snow
Congealed, the crocus' flamy bud to glow?
Say, what retards, amidst the summer's blaze,
Th' autumnal bulb, till pale, declining days?
The God of SEASONS; whose pervading power
Controls the sun, or sheds the fleecy shower:
He bids each flower his quick’ning word obey;

Or to each lingering bloom enjoins delay.”
SELBORNE, July 3, 1778.



“Omnibus animalibus reliquis certus et uniusmodi, et in suo cuique genere incessus est: aves solæ vario meatu feruntur, et in terrâ, et in aëre.”—Plin. Hist. Nat. lib. x. cap. 38.

“All animals have a certain definite and peculiar gait; birds alone more in a varied manner both on the ground and in the air."

GOOD ornithologist should be able to distinguish birds by their air as well as by their colours and shape; on the ground

as well as on the wing, and in the bush as well as in the hand. For, though it must not be said that every species birds has a manner peculiar to itself, yet there is somewhat in most genera at least, that at first sight discriminates them, and enables a judicious observer to pronounce upon them with some certainty.* Put a bird in motion and it is truly betrayed by its gait.”

gliding manner that the former are still called in the north of England and Scotland “gleds,” from the Saxon verb glidan, to glide. The kestrel, or windhover, has a peculiar mode of hanging in the air in one place, his wings all the while being briskly agitated. Hen-harriers fly low over heaths or fields of corn, and beat the ground regularly like a pointer or setting-dog. Owls move in a buoyant manner, as if lighter than the air; they seem to want ballast. There is a peculiarity belonging to ravens that must draw the attention even of the most incurious—they spend all their leisure time in striking and cuffing each other on the wing in a kind of playful skirmish; and, when they move from one place to another, frequently turn on their backs with a loud croak, and seem to be falling to the ground. When this odd gesture betides them, they are scratching themselves with one foot, and thus lose the centre of gravity. Rooks sometimes dive and tumble in a frolicsome manner; crows and daws swagger in their walk; wood-peckers fly volatu undoso, opening and closing their wings at every stroke, and so are always rising or falling in curves. All of this genus use their tails, which incline downward, as a support while they run up trees. Parrots, like all other hooked-clawed birds, walk awkwardly, and make use of their bill as a third foot, climbing and descending with ridiculous caution. All the gallinæ parade and walk gracefully, and run nimbly; but fly with difficulty, with an impetuous whirring, and in a straight line. Magpies and jays flutter with powerless wings, and make no dispatch; herons seem encumbered with too much sail for their light bodies; but these vast hollow wings are necessary in carrying burdens, such as

large fishes, and the like; pigeons, and particularly the sort called “smiters," have a way of clashing their wings, the one against the other, over their backs with a loud snap; another variety called tumblers, turn themselves over in the air. Some birds have movements peculiar to the season of love: thus ringdoves, though strong and rapid at other times, yet, in the spring, hang about on the wing in a toying and playful manner; thus the cock-snipe, while breeding, forgetting his former flight, fans the air like the wind-hover; and the green-finch in particular, exhibits such languishing, and faltering gestures, as to appear like a wounded and dying bird; the king-fisher darts along like an arrow; fern-owls, or goat-suckers, glance in the dusk over the tops of trees like a meteor; starlings as it were swim along, while missel-thrushes use a wild and desultory flight; swallows sweep over the surface of the ground and water, and distinguish themselves by rapid turns and quick evolutions; swifts dash round in circles; and the bank-martin moves with frequent vacillations like a butterfly. Most of the small birds fly by jerks, rising and falling as they advance; many of them hop; but wagtails and larks walk, moving their legs alternately. Skylarks rise and fall perpendicularly as they sing; woodlarks hang poised in the air; and titlarks rise and fall in large curves, singing in their descent. The white-throat uses odd jerks and gesticulations over the tops of hedges and bushes. All the duck-kind waddle; divers, and auks, walk as if fettered, and stand erect on their tail: these are the compedes of Linnæus. Geese and cranes, and most wild-fowls, move in figured flights, often changing their position. The secondary

remiges of Tringa, wild-ducks, and some others, are very long, and give their wings, when in motion, a hooked appearance.

Dab-chicks, moor-hens, and coots, fly erect, with their legs hanging down, and hardly make any dispatch; the reason is plain, their wings are placed too forward out of the true centre of gravity for rapid progression; as the legs of auks and divers are situated too backward.
