The area is filled with small blood vessels and provides heat for the eggs or young fledges.

After the eggs hatch, the young is helpless, vulnerable, and without feathers. After about 17 days they have all their feathers and at 21 days of age they are able to leave the nest. The baby birds are closely watched and fed by their parents until they leave their nest at about 2 to 4 months old. The fledgings can feed themselves at 3 weeks old though they still follow their parents around.
