Bird Skeletal Anatomy Diagram - Labeled Avian Skeleton for Study #2268184 (License: Personal Use)

This black-and-white anatomical drawing depicts a complete avian skeleton in lateral view, with major bones such as the orbit (orb), scapula (sc), humerus (hu), ulna (uln), radius (rad), femur (fem), tibiotarsus (tb), and tarsometatarsus (tmt) clearly labeled using standard abbreviations. The image emphasizes adaptations for flight, including the fused synsacrum, keeled sternum (not labeled but implied), and lightweight yet strong limb bones. It reflects early 20th-century zoological illustration style, prioritizing clarity and accuracy.
