Bird Foot Morphology: Anatomical Diagrams of Avian Digit Adaptations #3281039 (License: Personal Use)

This scientific illustration compares four avian foot types based on phalangeal and tarsometatarsal structure. Diagram A shows a typical anisodactyl foot (three toes forward, one back), B depicts a zygodactyl configuration (two forward, two back), C illustrates a pamprodactyl foot (all four toes forward, as in swifts), and D represents a syndactyl foot (toes II-IV fused at the base, common in kingfishers). Roman numerals indicate digits, with III typically bearing the main weight-bearing pad.
