The video spread quickly on the web posted by Twitter users keita_simpson, gaining nearly 9 million views.
The image shows a strange crow, as if standing by its wings. At the same time, the wings seemed to be like muscular arms, and did not see the bird's legs.
When birds sit down, they land and spread their tails, so they don't seem to have legs.
Netizens ask a lot of questions about birds. They asked if there was such a bird, its legs disappeared and what was happening to it.
The eagle researcher Keli Swift tried to explain the strange behavior of the crow from a scientific point of view.
'In fact, this crow is sunny. When birds sit down, they land and tail, so it seems they don't have legs, ' explains Keli Swift.
'In any case, this sunshine is a common behavior of birds. They often do it when it's hot. They do this to take care of the coat. Sun drying can reduce the number of bacteria and ticks, ' concluded Keli Swift.
