The only chicken in the world that has claws on its wings and flies like a bird
The hen is the last surviving member of an ancient bird lineage that branched off in separate directions 64 million years ago, shortly after the mass extinction of the dinosaurs.

Found in the Amazon and Orinoco of South America, the hoatzin (Opisthocomus hoazin) is considered the world's most mysterious bird.
The bantam has a long neck and a small head. It has a featherless blue face with hazel eyes and a bristly crest on top of its head.
The upper surface of the body of the chicken is dark gray, the lower surface of the body is light, the outer feathers of the wings are brown, the long tail is gray with a white tip.
The young have two claws on each wing. As soon as they hatch, they can use these claws and their feet to crawl around tree branches.
When predators such as large black hawks attack the nesting area, adult black-throated chicks will fly around noisily to distract the predators, while the young leave the nest and hide in the bushes.
They can swim underwater to escape danger, then use their clawed wings to climb back to the safety of their nest.
The claws on the wings of the young clawed chicken bear a remarkable resemblance to those of Archaeopteryx, an ancient bird known only from fossils.
However, it has also been hypothesized that the claws of the hen-claw are of more recent origin and may have evolved from the chicks' need to frequently leave the nest and climb vines and dense vegetation.
In 2015, a genetic study showed that the hen is the last surviving member of an ancient bird lineage that branched off in separate directions 64 million years ago, shortly after the mass extinction of the dinosaurs.
They are classified in the order Opisthocomiformes, the closest relatives of the fowls may be the order Fossils or the order Cucu.
Coots live in small flocks and nest in small groups. Their food is mainly leaves, sometimes eating flowers and fruits.
The digestive system of guinea fowl is unique among birds . They store special bacteria in the front part of their intestines to break down and ferment the plant material they ingest, just like cattle and ruminants.
They usually lay two or three eggs in a stick-shaped nest on a tree suspended over the water.
A noisy bird, the cockatoo produces a variety of raucous calls, including grunts, croaks, screeches, grunts, and grunting.
Currently, the banteng is at risk of decline due to habitat loss, mainly due to deforestation in the Amazon.
