The courtship display by the grey-crowned cranes is one of the best among the species of birds. They dance, jump and produce interesting calls to attract the mate. The most prominent feature of this fantastic African bird is its crest of golden feathers. The plumage of grey-crowned crane is mainly grey with pale-grey neck and black and white wings. They also have an attractive bright red pouch below their beak.
You might think of pigeons as… not that smart. But it turns out, they’re actually quite intelligent. In fact, one 2011 study published in the journal Science found that the birds are capable of doing math at the same level as monkeys. During the study, the pigeons were asked to compare nine images, each containing a different number of objects. The researchers found that the birds were able to rank the images in order of how many objects they contained. Put simply: they learned that the birds could count!
