What is significant about the Hoatzin?
hoatzin, (Opisthocomus hoazin), primitive chicken-sized bird of South American swamps, principally in the Amazon and Orinoco river basins. ... The hoatzin is the only bird with a digestive system that ferments vegetation as a cow does, which enables it to eat leaves and buds exclusively.
What makes the hoatzin different?
Hoatzins are sort of like flying cows
Those ruminating mammals have specialized sacs in their gut called a 'rumen', whereas Hoatzins have an enlarged esophagus and crop. The Hoatzin is the only bird in the world that uses these foregut compartments instead of a stomach to digest food.
Can the hoatzin fly?
Hoatzins are poor, clumsy flyers, especially in their early days. Hoatzin chicks are incapable of flight until 60 to 70 days after they are born. That's a long time to be vulnerable to predators. Luckily young hoatzins are equipped with claws on their wings, which they can use to climb branches.
How does the hoatzin keep predators away?
'Opisthocomus', its Latin name, comes from the feathers that run down its back. They have a big claw on the end of their wings that they use to protect themselves. Hoatzin chicks are able to hide underwater to escape from predators, but adult birds cannot swim.
What makes a hoatzin so unusual?
Due to specific type of diet, hoatzin digests its food with a help of bacteria in its crop. ... Food fermentation produces unique and unpleasant smell (a manure-like smell), which is why hoatzin is also known as "stinkbird" or "stinking pheasant". Amazonian people avoid hunting and eating hoatzin because of its smell.
Why is the hoatzin so smelly?
The hoatzin of the Amazon Basin is a folivore, or leaf-eater. This so-called 'stink bird' reeks of fresh cow manure or sweet-smelling hay, because of its unusual diet. ... The bird 'chews' leaves before swallowing, and ridges inside its crop help to break up the leaf bulk further so it can be processed more easily.
Do hoatzin lose their claws?
Hoatzins are the only living birds with functional claws on their wings, a trait they lose as adults. The chicks use their claws to climb back into trees after dropping in the water to escape predators.
What are hoatzin predators?
Hoatzin is vulnerable to nest predation. Eggs and chicks are preyed upon by monkeys, tayras (mustelidae) and other mammals, but also by avian predators such as falcons, hawks and eagles.
Do hoatzin keep their claws?
Once the danger has passed, they paddle to shore, and use their wing claws to clamber up the tree and back into the nest. The wing claws disappear by the time the Hoatzin matures, at which point the birds can pretty much pass as normal, at least from the outside.
Is the hoatzin a dinosaur?
Hoatzin Birds: A truly unique species
Genetic research published back in 2015 concluded that the hoatzin is the last surviving member of a genus of birds that branched off and evolved separately about 64 million years ago, around the time the dinosaurs became extinct.
What is the smelliest bird in the world?
Native to the Colombian rainforest, the world's smelliest bird is undoubtedly the hoatzin (Opisthocomus hoazin), a bizarre-looking bird variously classified with the pheasants, cuckoos, touracos, and even in a taxonomic group entirely of its own, which stinks like cow manure.
What does a hoatzin sound like?
Contact calls between birds in social groups are described by Strahl (1988) as a series of low grunts, usually 3-10 described as either "ohh" or "oww". When defending their nest and chicks from potential predators, Hoatzins make a loud, raspy, nasal, wheezy hiss (Strahl 1988, Thomas 1996).
How do hoatzin adapt to the rainforest?
The unique wing claws of young Hoatzins make them expert climbers. Young Hoatzins use flapping motion of their specialized wings along with alternating leg movements to swim under water. The Hoatzin is the only bird species to possess a specialized digestive system that allows it to eat leaves.
What layer of the rainforest does the hoatzin live in?
One of the strangest birds in the world is the hoatzin which jumps and climbs about in the canopy of South America. This chicken-sized bird has red eyes surrounded by bright blue skin and a crest of long thin feathers.
What is a Stinkbird?
Definition of stinkbird
1 : hoatzin. 2 : any of various birds (such as some wrens and sparrows) that leave a strong scent which may distract or confuse a bird dog.
