Ortalis ruficauda

The rufous-vented chachalaca is a member of an ancient group of birds of the family Cracidae, which are related to the Australasian mound builders. It inhabits northeast Colombia and northern Venezuela where it is called guacharaca, and the island of Tobago in the Republic of Trinidad and Tobago where it is known as the cocrico and is one of the country's two national birds. It is also found on Bequia and Union Island in the Grenadines where it may have been introduced.
