In this study the vascularization of the wing and the two main breast muscles of pigeons was investigated using classical anatomical techniques. Three groups of 9‐month‐old pigeons cadavers were dissected. Each group contained six animals. The cadavers of the group no. 1 were first fixed using 4% formaldehyde solution and the arteries filled with coloured latex. After coagulation we dissected the pectoral (pectoral and supracoracoid) muscles and the supplying branches of the pectoral trunk. We followed also the subclavian, the axillary, the brachial, the radial and ulnar arteries as they vascularized the wing. The cadavers of group no. 2 were used as fresh cadavers and perfused via the brachial artery in retrograde direction with methyl–methacrylate. After the polymerization, the bodies were placed in concentrated hydrochloric acid so the microvascularization of the great breast muscles and the arteries of the wings could be investigated. The arteries of the group no. 3 were filled with BaSO 4 solution after fixed with formalin and radiographed. Using this method we could represent the relation of the arteries to the bones. The breast muscles that move the wing are mainly vascularized by the pectoral trunk, which is the strongest branch of the subclavian artery and divides into the cranial, middle and the caudal pectoral arteries. Also the sternoclavicular artery is giving strong rami to the supracoracoid muscle by the lateral border of the coracoid. The subcutaneous thoracoabdominal vessels that supply the brood patches are branches of the pectoral trunk too. The brachial artery lies between the biceps and triceps brachii muscles on the medial side of the humerus and ramifies at the level proximal of the elbow joint to the stronger ulnar and weaker radial arteries. The radial lies cranially, covered by the pronator muscles and gives two branches, the deep and superficial radial arteries. The ulnar artery also gives off two: the superficial and deep ulnar arteries, which supply the flexor muscles and vascularize the distal part of the wing.
