Passenger Pigeon (Ectopistes migratoria), a native of temperate North America. The tail is very long, graduated, and pointed. The male is about eighteen inches in length; the upper parts generally blue, with metallic gloss on neck; under-surface brownish-red. The female is a little smaller, and her plumage is less brilliant. The flesh is valued for the table. The migrations of these birds are undertaken in search of food.
