OAKLAND, Calif. -- Sixteen baby herons and egrets have been rescued after their tree collapsed in Oakland, hurling them from their nests to the pavement.

International Bird Rescue says it got a call Wednesday after a ficus tree that was serving as a rookery split in half and partially fell.

Rescuers took the snowy egrets and black-crowned night herons to the group's rescue centre in the San Francisco Bay Area city of Fairfield.

Some of the chicks are only days old.
