Abstract. The wings of all flying birds consist of two parts: the arm wing and the hand wing. Cross sections through the arm wings have a round leading edge, a cambered shape, and a sharp trailing edge. The hand wing consists mainly of the primary feathers; its cross section is flat, and the leading edge and the trailing edge are both sharp.The avian stomach is divided into a glandular and muscular section. Food passes first into the proventriculus, which secretes mucous and enzymes for chemical digestion. Next is the muscular ventriculus or gizzard, which grinds the food into smaller particles. This improves the efficacy of chemical digestion and is better developed in birds that ...Structure of the bird's wing with three joints. Source publication +2. ...
