Labeled bird

“When a new bird is seen, the observer should write an accurate description of it in his notebook, giving the length from the tip of the bill to the end of the tail; the color of the crown and sides of the head, back, wings, tail, breast, and belly; length, shape, and color of the bill; length, position and arrangement of the tail feathers; and the method of feeding and manner of flight as well as its characteristic song.” — Davison, 1906
