​What are birds?

A bird is a vertebrate, a creature with a backbone inside their body. They evolved from feathered dinosaurs. Birds are fascinating, magnificent animals and are also known as avians. They have character traits we can easily identify with: cheeky and shy, gentle and vicious, faithful and faithless. Avians are a part of our world, yet with a flick of their tails they lift into the air and vanish into a world that we can only envy.
