Buffon observes that it is frequently caught in the winter, when it is fat and delicious eating. * * * * * The Moor Buzzard, Duck Hawk or White-headed Harpy (_Falco Æruginosus_, LINN.; _Le Busard_, BUFF.) is in length above twenty-one inches. The bill is black; cere and eyes yellow; the whole crown of the head is of a yellowish white, lightly tinged with brown; the throat is of a light rust colour: the rest of the plumage is of a reddish brown, with pale edges; the greater wing coverts tipped with white. The legs are yellow; claws black. Birds of this kind vary much; in some, the crown and back part of the head are yellow; and in one described by Mr. Latham, the whole bird was uniformly of a chocolate brown, with a tinge of rust colour. The moor buzzard preys on rabbits, young wild ducks, and other water-fowl; and likewise feeds on fish, frogs, reptiles, and even insects. Its haunts are in hedges and bushes near pools, marshes, and rivers that abound with fish. It builds its nest a little above the surface of the ground, or in hillocks covered with thick herbage: the female lays three or four eggs of a whitish colour, irregularly sprinkled with dusky spots. Though smaller, it is more active and bolder than the common buzzard, and, when pursued, it faces its antagonist, and makes a vigorous defence.—_Bewick._—_Latham._ BY-LAW, _s._ By-laws are orders made for the good of those that make them, farther than the public law binds.

CACKLE, _v._ To make a noise, as a goose or hen. CACKLER, _s._ A fowl that cackles. CADDIS or CAD-BAIT, _s._ A kind of worm or grub. The several kinds of cadews in their nympha, or maggot state, thus house themselves; one sort in straw, called from thence straw-worms; others in two or more parallel sticks, creeping at the bottom of brooks; a third, in a small bundle of pieces of rushes, duckweed, &c. glued together, therewith they float on the surface, and can row themselves about the water with the help of their feet; both these are called cad-bait. It is a curious faculty that these creatures possess, of gathering such bodies as are fittest for their purpose, and then so gluing them together, some to be heavier than water, that the animal may remain at bottom where its food is, and others to be so buoyant as to float, and there collect its sustenance; these houses are coarse, and show no outward art, but are within well tunnelled and have a tough hard paste, into which the hinder part of the maggot is so fixed, that its cell can be drawn after it without danger of leaving it behind, and it can also thrust out its body to reach the needful supplies, or withdraw into its covering for protection and safety.
