Puffins are probably our most colourful seabird. In winter the bill is a dull orange and the face is black, but in summer the birds grow some horny plates on the beaks which are bright red, blue and yellow, and the 'gape' at each corner of the mouth turns bright yellow. This distinctive colouring has earned it the nickname of 'sea parrot'.
In spring and early summer puffins come ashore to have their young. They nest in burrows which they can dig themselves, or they may use an old rabbit burrow. The nest is lined with feathers, grass and other soft items that the birds can find, like bits of sheep wool. Just one egg is laid which takes about six weeks to hatch.
The chicks (pufflings) stays underground out of the sight of predators, while the parents go out to catch sand eels and small fish for the chick. It takes about seven weeks before the chicks are ready to leave the burrow. They usually leave the buurrow at night, and may not return to land again for five years, when they will be ready to breed themselves.
