Toucan - Cool Beak


The outrageously big beak helps to keep the bird cool in the heat of the tropical day.

A toucan's beak has a rich supply of blood vessels running along its surface so the bird's bill is suited to act as a means of radiating heat to keep the core temperature of the body stable – the bill also accounts of between 30 and 50 per cent of the bird's surface area.
