The pelicans are among the largest aquatic birds and can be recognised due to their large beak with a roomy extendable pocket. All in all, a genuine fishing net! As well as being used to capture prey, this mouth bag ebles the Pelican to refresh itself during very hot periods. Pelicans are to be found in waters the world over and are often present near rivers, lakes and oceans, where they live in colonies. For the chicks, they organise a kind of "child-minding" system. Did you know that pelicans can only take off after a substantial run-up on the water due to their weight?
