Cuckoo Bird Illustration - Vintage Scientific Drawing #3392594 (License: Personal Use)

This monochrome engraving depicts a cuckoo (Cuculidae family) in profile, gripping a slender branch with strong zygodactyl feet. The artist uses precise cross-hatching to render feather texture, barred underparts, and the distinctive long tail with spotted markings. The bird’s beak is open as if vocalizing, capturing a moment of natural behavior with scientific accuracy.
