Two Dalmatian Pelicans （卷羽鹈鹕） were born at the San Diego Zoo in California last month. Both of them are fine. One of them， in fact， is doing too good.

He is just a month old， but he is around 12 pounds（5.4 kilograms） heavy. The zoo staff must watch the pelican to make sure that he does not eat too much. If he eats too much， he will grow too quickly.

The two pelican brothers do not live together ─ that would be dangerous. Pelican brothers often attack each other. When they are both old enough， they will join the rest of the flock （鵜鹕群）.
