noun. Plural form of bird.

"Roaming about in the woods with hatchet in hand, like a backwoodsman, followed by a troop of dogs; starting up of birds, snakes, hares and foxes, and examining the various kinds of trees, flowers, and birds’ nests, was at least, a change from the monotonous drag and pull on shipboard."
