Famous Osprey Recovering at WildCare
By Alison Hermance
As you probably know, WildCare doesn’t name our Wildlife Hospital patients (not least because we admit over 3,500 of them a year!) but this fledgling Osprey arrived already came with a name. He’s known as Tam, one of three fledglings in the much-watched Golden Gate Bird Alliance Osprey webcam nest on the Whirly Crane in Alameda. Tam grew up in his crane-top nest under the care of his parents, known as Richmond and Rosie. The Osprey pair has successfully raised numerous broods of chicks, including Tam and his siblings, dubbed Shasta and Lassen, by their fans.
Osprey chicks begin flying when they are about 60 days old. On July 5, 2020, cam-viewers watched the fledgling Tam make his precarious way up the crane to try out his wings, losing his balance but regaining it many times. Fledgling birds are a lot like teenagers; they don’t have all the control they need over their gangly limbs. Tam’s clumsy adventure was typical of young Osprey his age. The video feed captured Tam eventually tumbling to the ground, where he was rescued by one of the trained observers monitoring the nest, and was brought to WildCare.
Tam had always been the smallest and least active of the three chicks. He arrived at WildCare alert but quiet, and demonstrating the symptoms of head trauma.
A full exam and x-rays found no injuries, but our team was concerned that he hadn’t been able to get himself back up onto the crane after his aborted test flight. A fully healthy fledgling Osprey should be able to hop-fly back to his nest, but Tam had not been able to do so.
However, with Tam’s head trauma symptoms resolved after several days in care, our team made the decision to give him a test flight in a large aviary. As long as the test flight went well, we planned to return him to his parents’ care that day. Osprey are incredibly difficult patients to have in captive care, so returning him to the nest would give him the best chance of success.
It turns out we were right to be concerned about Tam’s overall health.
Very unexpectedly Tam fractured his leg in the aviary that morning. It was a shock to all, as there is no discernible reason for the injury. The bird’s original x-rays gave no clue that his leg might be an area of concern, and he did not have a hard impact landing.…
