Burhinus nanus

† Burhinus nanus was a small, extinct species of thick-knee known from subfossil material from the Bahamas. As a member of the family Burhinidae, it was a carnivorous bird feeding on invertebrates and small prey. Its diminutive size relative to mainland thick-knees likely reflects insular dwarfism, a widespread evolutionary trend among Caribbean island-dwelling birds. Habitat loss and human arrival likely contributed to its extinction.
