The descendants of the dinosaurs defend themselves very well since they are more numerous than the humans. And despite the fact that many chicks die during their first weeks. The variety of species is extraordinary, as there are more than 10,461 species of birds according to the BirdLife organization!

There is at least 31 billion of birds on Earth. What remains ten times less than mammals.

We might have thought that the sparrows were the most populated species, but in fact not, the chicken that is massively raised in most countries. With very often lack of ethics. Namely, fast-growing chickens, which reach adult size after one month (instead of 6 months) and still have their little chick head. There are a lot of them that do not have time to grow up and are quickly deprived of food, whereas grain bins are raised in height over days.

There are not so many pigeons. In fact this bird is not widespread everywhere, in many countries it is mostly found in cities.

We can see that condors are very rare. They are among the largest birds with wingspan that can reach 10 feet.
