The Bahaman caracara (Caracara creightoni), also known as Creighton's caracara,[1] is an extinct bird of prey. It is known only from a few fossils discovered in the Bahamas and Cuba.[2] Caracara creightoni was a scavenger and opportunistic species instead of a predator like its sister extant species (C. plancus). It lived during the late Pleistocene to the beginning of the Holocene era.
C. creightoni stood 58 cm tall, was short-winged and likely a poor flier.[2] This species went extinct as a result of humans arriving on its home islands and wiping out the bird's prey species.[1] A 2,500 year old C. creightoni femur from an Abaco Islands blue hole yielded a nearly complete mitochondrial genome.[3] The DNA shows that the species was closely related to the crested caracara. The two species last shared a common ancestor between 1.2 and 0.4 million years ago, during the Pleistocene.
