Jay, or Corvus g/avdarius, L. a well-known British bird, remarkable for its beauty. It is about 13 inches in length ; its forehead is white, streaked with black; the head is covered with a tuft of long feathers, which the bird erects at pleasure into the form of a crest: the whole neck, back, breast and belly, are of a faint purple colour, intermixed with grey.

Jays build chiefly in woods, where they construct their nests with sticks, fibres of roots, and tender twigs, in which the females deposit from five to six eggs of a dark olive colour. They feed on acorns, as well as every kind of grain, and are very mischievous, frequently destroying young chickens and eggs: nor do they spare birds that have been caught in a trap, or entangled in bird-lime.— The most effectual method of taking them is that already pointed out in the article Jack-daw.
