Toucans, perhaps best known for their colourful large beaks are birds from Ramphastidae family found in neotropics. There are around 40 different species of toucans all of which have these large beaks. It was initially thought that the large beak was used to capture and eat fish but it is now known that toucans actually use their beaks to reach for fruits and find food inside the tree holes. Even though the beak is quite large it is incredibly light because of is very porous structure (see the image with the cross-section of the beak).

And there’s one tucan that you can see in sky at night- the constellation Tucana, a member of the Southern Birds group, can be seen from the Southern Hemisphere (the middle bird in the sky atlas at the bottom).
