How does bird flight work?

If you thought it was with the flapping of the wings, you got right to the point! After all, without them, birds would not be able to fly. But let's get to the details of this operation…

Birds are descended from a small group of dinosaurs that developed feathers. In the beginning, they probably served to maintain body temperature or as a form of garnish to help find a breeding partner.

Throughout evolution, these dinosaurs' forepaw feathers have increased in size and consistency – especially in ancestral birds such as Archeopteryx. Thus, the wings emerged, structures that enabled the gradual development of flight.

By flapping their wings, the birds generate an impulse that makes them leave the ground. To get this boost, however, they need to rely on strong muscles in the chest region.

Another characteristic of these animals that favors flight are the pneumatic bones, that is, they have air inside their structure. No matter the size of the birds – whether it's a 15 kg condor or a three gram hummingbird, the pneumatic bones give them more lightness and flexibility, in addition to making them more resistant to fractures.

Flying is a huge evolutionary advantage, which has allowed birds to explore many environments. Adapting to life in such different places on our planet, they have diversified a lot: there are birds that live in cold and heat; birds that feed on fish or eat decaying organic matter, nectar, fruits and other foods; birds that live in forests, fields and even those that like to swim in the sea.

We can say that the evolution of this group of animals was a success - such a success that it brings lessons even for us humans: it was by observing the physics of bird flight, for example, that we were able to build planes! […]
