This work is the first myological dissection performed in detail on the hin-dlimb of Tyto alba. Six specimens were dissected and their muscle masses wereobtained. T. alba has the classical myological pattern present in other speciesof Strigiformes, such as a well-developed m. flexor digitorum longus and theabsence of the m. plantaris, flexor cruris lateralis and ambiens. Also, T. albalacks the m. extensor propius digiti III, m. extensor propius digiti IV and m. lum-bricalis, present in the Strigidae. Hindlimb muscle mass accounts for 14.13% oftotal body mass, which is within the range of values of both nocturnal (Strigi-formes) and diurnal (Falconidae and Accipitridae) raptors. This study providesimportant information for future studies related to functional morphology andecomorphology
