The Hoatzin, also called the stink bird by breeders because of its odiferous droppings, is a pheasantlike bird that measures about 25 inches in length and has a disproportionately small head for its elongated neck and plump body. These birds are very loud, making them a poor choice for owners or breeders in heavily populated cities.

Tityra birds are rather small but avid flying insect catchers. Native to South America's tropics, they lack the plentiful colorings of other tropical birds. You can identify these tropical birds by their black and grey markings. Tityra birds do not have loud calls but communicate with a kind of drone. These birds do best housed in a spacious aviary. A dependable pocket scope--such as the Brunton Echo--can help you locate these fast birds.

Keep your ears open for the trilling cry of the shining honeycreeper. These birds live high up in the trees and could be easy to miss--they are only about 4 inches long--if not for their bright blue coloring and bright yellow legs. If you decide to keep this tropical bird, make sure that you have a tall aviary and plenty of room; honeycreepers are very social birds and live in groups.
