Abstract

Summary: This work is the first myological dissection performed in detail on the hindlimb of Tyto alba . Six specimens were dissected and their muscle masses were obtained. T. alba has the classical myological pattern present in other species of Strigiformes, such as a well‐developed m. flexor digitorum longus and the absence of the m. plantaris, flexor cruris lateralis and ambiens . Also, T. alba lacks the m . extensor propius digiti III, m. extensor propius digiti IV and m. lumbricalis, present in the Strigidae. Hindlimb muscle mass accounts for 14.13% of total body mass, which is within the range of values of both nocturnal (Strigiformes) and diurnal (Falconidae and Accipitridae) raptors. This study provides important information for future studies related to functional morphology and ecomorphology.
