Bird Wing Anatomy: Skeletal Structure and Feather Arrangement Explained #1793281 (License: Personal Use)

This 19th-century engraved illustration meticulously depicts the osteological and integumentary components of a bird’s wing, including the humerus (h.), radius (r.), ulna (u.), carpometacarpus (c.), and phalanges (p.f.), alongside primary (p.f.) and secondary feathers (s.f.). Fine linework highlights muscle attachments (m.c.) and the layered arrangement of covert and flight feathers, demonstrating biomechanical adaptations for powered flight. The image serves as both an educational tool and historical reference in comparative anatomy.

Used in academic textbooks, museum exhibits, and online biology resources to teach avian morphology; targets students, educators, and researchers seeking visual understanding of flight mechanics and evolutionary adaptations in birds.
