The research present work deals with the anatomical description of the jaw muscle of two different birds; the common kestrel, Falco tinnunculus and the budgerigar, Melopsittacus undulatus and the analysis of the mechanical performance of jaw system during the feeding process. In the kestrel, the jaw muscles has complex muscle-fibers with multiple directions and are provided with a high complex aponeurotic and tendinous system, those properties of the muscle enable the adductor muscle of the kestrel potentially to produce a strong force bit. The bite force of the kestrel produces only from the mandible. While the jaw muscles of the budgerigar enable the movement of the upper jaw, as well as, the mandible.
