From an article in the "Ojai Valley News.com" on Victor from the Fraser Point eagle nest (the newest info comes within about the last 6 paragraphs of this article):
Sick bald eagle recovering at ORC Perry Van Houten Jul 28, 2022 Updated Jul 29, 2022

The sick bald eaglet rescued from Santa Cruz Island is shown standing on his own this week at the Ojai Raptor Center.
A young bald eagle rescued from the Channel Islands and now being cared for at the Ojai Raptor Center continues to recover from metal poisoning.
Thirteen-week-old bald eaglet 22-635 from Santa Cruz Island arrived at the Center on July 11, after his rescue by Dr. Peter Sharpe of the Institute for Wildlife Studies.
Sharpe became concerned about the fledgling after viewers of a live webcam noticed the bird had difficulty standing.
According to ORC staff veterinarian Dr. Stephany Lewis, the bird was alert and responsive upon arrival: “He was vocalizing. He would try to stand, but just had difficulty getting all the way upright and getting his legs underneath him with enough strength to stand up.”
Lack of coordination, weakness in the legs and the inability to stand can be caused by a number of neurologic conditions, Lewis told the Ojai Valley News.
She ran a gamut of tests on the sick fledgling to try to pinpoint the cause of its ataxia, including basic bloodwork to look for evidence of infection and to check on white and red blood cell counts.
Using an in-house analyzer, Lewis checked the bird’s blood lead level, which turned out to be low, so lead toxicity was ruled out.
X-rays did not show signs of trauma or evidence of ingested metal, and a CT scan that looked for evidence of spinal trauma came out normal, Lewis said.
Another test looked for evidence of West Nile Virus, while another checked for avian influenza, which so far has been diagnosed only in Northern California. “But it’s been known to cause neurologic signs in raptors, and it has nearly 100% mortality in raptors,” Lewis said.
A further blood panel was done to look for a wide variety of toxic heavy metals. The bird was retested for lead, while Lewis also looked for selenium, mercury, arsenic and zinc. “The only thing that came back positive was the bird had a high zinc concentration in his blood,” she said.
Exposure to zinc can come from ingesting pennies minted after 1982 or wire coated with zinc, or from chewing metal objects such as galvanized wire. Zinc can also be released into the environment from mining operations, according to the ORC.
Treatment of the eaglet has included injectable and oral medications, antifungals and antibiotics, and fluids to try to flush the toxin from the bird’s system.
Though he needs to be fed by hand, the bird is eating healthfully and has gained a little weight since arrival, Lewis said.
While Lewis still sees signs of clumsiness, the eaglet seems to be doing much better. “He’s a lot stronger, a lot brighter,” she said. “He’s not 100%, by any stretch, but he’s gone from lying down all day long to standing up and perching all day long.”
Neurologic issues in wildlife caused by metal poisoning can take several weeks to fully resolve, according to Lewis: “He still has a long road. There is still a risk that there could be permanent neurologic damage from the zinc. I’m hopeful that’s not the case.”
Even if the eaglet makes a full recovery, the bird named “Victor” by the public could remain at the center for several months, Lewis said.
Any long-term residual effects from the zinc could make the bird nonreleasable, according to Lewis. “But he still continues to move in the right direction,” she said, “and we’re pleased at how he’s doing so far.”
