We think it’s safe to say that most citizens of the Bay Area now know what a Black-crowned Night Heron is….
The subject of extensive media attention in the New York Times, San Francisco Chronicle, local TV news and NBC’s The Today Show, five baby Black-crowned Night Herons — a federally protected species — were injured in early May after falling from their nests during a tree-trimming incident at a U.S. Post Office location.
All herons were brought to WildCare in Marin County for initial treatment before transfer to International Bird Rescue San Francisco Bay center, which specializes in herons and other aquatic species.
The injured herons have been treated for injuries sustained from the fall, with one baby heron suffering a fractured mandible that required surgery and healed remarkably. Ernesto Pulido, the proprietor of the tree-trimming business, immediately stepped forward to pay for the care of these animals.

Fast-forward to this past Saturday, where we were proud to work with Golden Gate Audubon Society on a release event at Martin Luther King Jr. Shoreline Park in Oakland. Four of the five herons from this incident were successfully released; the fifth is still in care but doing well (a fifth bird ready for release joined the other four at MLK Shoreline’s New Marsh). Thank you to Mr. Pulido as well for stopping by!
These are some of the dozens of herons we’ve cared for this season. You can support their ongoing care here.
Other good news: Our friends at Golden Gate Audubon have put together a wonderful pamphlet on tree-trimming and baby birds season that you can download here. A Spanish-language version will be released soon.
And thank you to all the birders who came out to see our patients off! We were happy to see these young herons start hunting for prey at the marsh within a half hour of release.
