The black-crowned night heron is a medium-sized, stocky bird with a distinctive, short, thick neck and a large, flat head. Its broad, rounded wings and short, pointed bill complement its compact appearance. The bird’s plumage includes a striking black cap and back, contrasting with grey wings and tail, and a white belly. Notably, the black-crowned night heron’s legs are yellow-green, turning pink during the breeding season, adding a touch of seasonal vibrancy to its appearance.
