OAKLAND — An animal rescue group is asking for help caring for 89 baby snowy egrets and black-crowned night herons left homeless last week after a tree fell in downtown Oakland.

International Bird Rescue said Wednesday it needs donations and volunteers to help feed and care for the baby birds rescued after an old ficus tree serving as a rookery split in half and partially fell last week, said JD Bergeron, the group’s executive director.

The group is caring for 89 young birds and eggs rescued from the tree including, 50 snowy egrets and 22 black-crowned night herons. It also rescued 17 eggs that need intensive care and round-the-clock support. Another 20 birds died when the tree fell.

The rescue group was already taking care of more than 200 Bay Area water birds at its busy hospital in the city of Fairfield, Bergeron said.

The youngest of the birds need care for at least six weeks. The oldest could be ready to fly in the next week or two, Bergeron said

“But what it does mean every single day is feeding the little ones every 60 to 90 minutes, keeping all the birds in a clean enclosure, proper food and warmth, water, (and) daily checks to make sure their weight and their health status are good,” he said.

“A lot of these birds did suffer trauma from falls so we have to take care of any wounds that came from that as well,” he added.

The birds, which breed in large groups, began using the massive and old leafy ficus trees in downtown Oakland for nesting about 10 years ago after non-native vegetation was removed from nearby Lake Merritt, scaring them away, said Cindy Margulis, executive director of Golden Gate Audubon Society.

“Most of those trees are really enormous canopies and their roots are underneath concrete so they cannot spread to get the support they need and gravity takes its toll,” Margulis said.

Biologists have identified two trees and have placed speakers in them that broadcast the sounds of a breeding colony, decoys of herons and egrets and nests left over from other breeding seasons to get the birds to raise their chicks there.

“They are visiting the destination sites so, that tells us there is interest and that’s very encouraging,” she said.
