Topic: Opisthocomidae

  Cuckoos and Their Relatives
The order Cuculigormes contains three rather different divergent families that are sometimes placed in their own orders; the family of cuckoos, roadrunners, anis, and their relatives (Cuculidae); the family of touracos (Musophagidae); and the family of the South American hoatzin (Opisthocomidae).
Because of the gross similarities between Archaeopteryx and some cuckoos, touracos, and hoatzin, some taxonomists consider Cuculiformes among the most primitive of living avian orders.
It is a long-tailed, chicken-like bird that exists on a diet of leaves and fruit.

  Hoatzin - Wikipedia, the free encyclopedia
There has been much debate about its relationships with other bird species.
It has been given its own family, the Opisthocomidae, and was previously grouped with the gamebirds or with the Gruiformes because of a similarity to the trumpeter family.
Sibley considered it more likely to be a cuckoo, another speculative placement for the Hoatzin, although this is disputed because the cuckoos have zygodactyl feet (two toes forward, two backward), whereas the Hoatzin has the more typical three toes forward, one backwards.

A morphofunctional analysis of the feeding apparatus was conducted from an evolutionary perspective on the hoatzin (Opisthocomidae), some cuckoos (Cuculidae) and some turacos (Musophagidae).
The morphofunctional analyses give results different from what is known for the Galliformes and allow the construction of the hypothesis of two trophic adaptive pathways.
One followed by the Cuculidae would have led to the consumption of a large range of arthropods, including toxic species; the other, followed by the Musophagidae and Opisthocomidae, would have led to the consumption of plant parts.

 A NEW BIRD (FAMILY CRACIDAE) FROM THE EARLY OLIGOCENE OF SOUTH DAKOTA   (Site not responding. Last check: 2007-10-08)
This projection, the postarticular process, is not so uniform in the Galliformes as might be supposed.
Although it is well developed in the Phasianoidea, it is reduced to a small, sharp point in the Opisthocomidae, and varies in the Cracidae from small and straight in Pipile to well-developed in Penelope and Crax.
Furthermore, the process can readily be broken off, as shown by its frequent accidental absence in modern eracid skeletons in museum collections.

 Biodiversity-Hoatzin
These unique birds are considered a relic from the age of the dinosaurs.
They represent the only living member of the family Opisthocomidae, and its close relatives probably died out long ago.
These chicken-sized birds weigh less than a kilogram (2 lbs) and have a body length of 61-66 cm (24-26 inches).

 Birds of Guyana: Hoatzin (Opisthocomus hoazin)
Mix in a bird call of hoarse cries, hisses, and grunts that is compared to a heavy smoker, and you get a bird that’s alternately described as majestic and punk rock rebellious, depending on the point of view.
The Hoatzin is such a bizarre species that after being shuffled through several bird orders, including the Gruiformes, Galliformes, and the Cuculiformes, researchers eventually put it in its own order: the Opisthocomidae.
Hoatzins are largely found in lowland swampy areas of the Amazon and Orinoco basins of South America.

These birds are also believed to communicate very well within their species.
Hoatzin is the only specie of its own family Opisthocomidae.
They are weak flyers and feed mostly on leaves of various plants but also on fruits and flowers in limited extent.

The chicks must dig their own way out of the mound, at which time the male leaves and the chicks disperse.
Family: Opisthocomidae (Greek: opisthen = "behind" + komys = "bundle or sheaf"...referring to the crest, perhaps, or the tail???)
The Hoatzin (Nihuatl: uatzin = "pheasant") is quite controversial, some authorities would put it in its own order, all by itself.

 Guyana Birding: Birdwatching Tours in South America’s Last Frontier
Hoatzins are found along rivers and creeks in the Upper Demerara River-Berbice area in Guyana, and are easily seen because they often live in large groups and rarely stray far from their principal locals, probably due to the fact that they're poor fliers.
Indeed, Guyana's national bird is such a bizarre species that it was put in its own order, the Opisthocomidae.
