Observing the flights of a bird over the same place, scientists noticed that it would never sit on a flower, where it had already drunk all the nectar.
The scientific community is amazed at how the millet-sized hummingbird brain can memorize. Despite its size, this bird uses its mind as much as possible.

But on the other hand, like most birds, most of all she needs freedom. She cannot be poultry.
