New discovery of the world's most dangerous bird knife-like claws

Scientists have recently discovered why the ostrich-headed ostrich bird is strangely shiny.

The crested ostrich is considered the most dangerous bird in the world. The dagger-like long toes of a bird of this species caused the death of a man in Florida last year.

But what excites scientists about this bird is its distinctive appearance. With shiny black feathers, a blue collar, turquoise, magenta and a hard crest on its head, this bird looks like a "fashioned dinosaur".

"It is over a meter tall and quite heavy. Their bones are very strong. This bird can certainly cause injury to the enemy," said Chad Eliason, a postdoctoral fellow at Field Museum in Chicago and is the author of the paper. Imitation of a scientific paper on crested ostriches, published on May 13 in the journal Science Advances. "There are many stories about their dangerous kicks. They help you identify birds that have a relationship with dinosaurs."

Each crested ostrich's three-toed feet have a 10-cm-long claw that can hurt a predator with just one kick, according to the San Diego Zoo. It can also run at speeds of up to 50 km / h in dense forests and jumps up to 2 m.

New research on feathers taken from a dead bird reveals what makes crested ostrich feathers black.

Unlike in other glossy-feathered birds such as hummingbirds or ravens, the ostrich-shaped ostrich's feathers are made up of feathered feathers, not fluff, or filaments on a feather.

Because the feathers on the feathers of crested ostriches are quite sparse, the feather pillars are exposed to more light in the "thick-feathered" birds , causing these crested ostriches to shine.

"The gloss of this bird's feather lies in a completely different place (compared to other birds). Imagine a feather like a tree, the gloss of an ostrich's feather in the trunk, not the trunk. tree branches, " Eliason explained.

Three species of crested ostrich live in areas north of Queensland, Australia and New Guinea. Their food is fruit.

Research shows that the mechanism that creates the unique gloss of crested ostrich feathers evolves over time.

Eliason suspects that flightlessness may have enabled the bird to evolve to get the exotic feathers it is today.
