Completion of this project would be welcomed for more reasons than resolution of hoatzin relationships. More recently, Houde embarked on sequencing the entire genome of the hoatzin. The hoatzin is the national bird of Guyana. The hoatzin is sedentary and widespread in suitable habitat. The hoatzin is pheasant-sized, but much slimmer. The Hoatzin is pheasant-sized, but much slimmer. The hoatzin is found in the rainforest of the Amazon. The hoatzin is a stunning, colourful bird from South America. The hoatzin is an example of a flighted, folivorous bird. It has evolved independently in several groups of mammals, and also in the hoatzin bird. The hoatzin therefore remains fairly common in a large part of its range. Hoatzin embryos are known to develop very quickly compared to other birds. The hoatzin lives in tropical forested wetlands of 200 to 500 meters elevation. However, hoatzin chicks have claws on their wings which they use for climbing.
