There are two subspecies[1]:

  • C. u. uncinatus:
  • C. u. uncinatus mirus: Grenada Kite:

Both of these last two subspecies are considered to be full species by some authors[3], [4] and both are critically endangered.

Two additional subspecies: aquilonis and megarhynchus are generally considered invalid[2].


Prefers the lower canopy in tropical rainforest and cloud forest, secondary-growth and riverine woodlands, swamps and savannas.


Perches high in trees and can be difficult to see. Not a shy bird.


Their main diet consists of snails; Cuban birds are also known to eat slugs.
