Chachalacas are mainly brown birds from the genus ''Ortalis''. These birds are found in wooded habitats in far southern United States (Texas),〔 In the 1920s Howard E. Coffin introduced a breeding population of chachalacas to Sapelo Island, and this breeding population still exists.〕 Mexico, and Central and South America. They are social, can be very noisy and often remain fairly common even near humans, as their relatively small size makes them less desirable to hunters than their larger relatives. They somewhat resemble the guans, and the two have commonly been placed in a subfamily together, though the chachalacas are probably closer to the curassows.〔 (Free version )〕 The generic name is derived from the Greek word όρταλις, meaning "pullet" or "domestic hen." The common name is an onomatopoeia for the four-noted cackle of the plain chachalaca (''O. vetula''). Mitochondrial and nuclear DNA sequence data tentatively suggests that the chachalacas emerged as a distinct lineage during the Oligocene, somewhere around 40-20 mya, possibly being the first lineage of modern cracids to evolve; this does agree with the known fossil record - including indeterminate, cracid-like birds - which very cautiously favors a north-to-south expansion of the family.〔 ==Species== * Plain chachalaca, ''Ortalis vetula'' * * Utila Island chachalaca, ''Ortalis vetula deschauensei'' (not seen for many years until rediscovery in 2005〔Glowinski, S.
