From the Trees to the Streets to Safety
By Ryan Nakano
On the corner of 12th and Harrison and along the perimeter of the Oakland Museum of California, nesting herons and egrets make a home among 10 large ficus trees. Unfortunately for many chicks, the streets below spell only danger.

“The rookery in downtown Oakland is not a very healthy place for these birds to be nesting, as there is nowhere for their chicks to make the next steps into adulthood nearby,” Rebecca Duerr, the International Bird Rescue Director of Research and Veterinary Science, said. “Consequently, they (chicks) often fledge into the street and either starve or get hit by cars. Sometimes they land badly and fracture bones.”

In January, the Oakland Zoo put out a call, offering four part-time positions responsible for rescuing these birds in downtown Oakland. Reinstating the Heron and Egret Rescue Program, the Oakland Zoo is now taking the lead in protecting fledgling Black-crowned Night Herons and Snowy Egrets from unsafe living conditions.
“We’re just now in the early phases of launching the program, but a large part of it will be going down there to check it out. Everyday the Oakland staff will scout in the morning and then go back in the afternoon,” Colleen Kinzley, Oakland Zoo Vice President of Animal Care Conservation and Research, said.”
Unfortunately, the problem of injured and unsafe heron and egret chicks in these areas is not new. Ever since they were spotted breeding downtown in 2010, they’ve faced the inherent dangers of nesting in an urban environment.
In 2015, in response to tree trimmers knocking down several active nests, Golden Gate Bird Alliance, the Oakland Zoo and the International Bird Rescue formed a partnership to rescue threatened herons and egrets in downtown Oakland.
In 2017, a group of developers removed and pruned back many of the trees that were once used by the birds as nesting sites. During this process they worked with wildlife ecologists to strategize around relocating the nests to Lake Merritt in hopes that the herons and egrets would follow. After an unsuccessful season of relocation, the city decided to end monitoring and relocation attempts.
With no permanent solutions, Black-crowned Night Herons and Egret fledglings continue to end up on the street, making the rescue program an essential animal welfare project.

After six years partnering with Golden Gate Bird Alliance, the Oakland Zoo hopes this dedicated three-year program will provide structure to the historically ad-hoc process for finding these vulnerable birds.…
