“ Acorns have been frequently taken from the crops of these Ducks.The Pintail, according to Goss, seldom dives, and it never does so while feeding, but in searching in the water for its food immerses not only the head but a large portion of the body. It is an odd sight to see a flock thus tipped up and working their feet in the air, as if trying to stand upon their heads. They move about with a graceful motion of the head, and with tail partially erect, and upon the land step off with a dignity of carriage as if impressed with the thought that they are no common Duck. ”
