✨ Happy Freedom Friday! ✨
These two Western Grebes arrived at our clinic after being contaminated with oil. One had a large patch of tar covering its breast, while the other had oil scattered across its feathers.
For aquatic birds like grebes who spend most of their life on the water, healthy feathers are essential. Their feathers trap a layer of air next to the skin, helping keep them warm, dry, and buoyant. When oil coats those feathers, that waterproofing is lost, leaving birds cold, stressed, and unable to forage effectively. Oil can also burn the skin and be ingested during preening, causing serious internal health problems.
Where does the oil come from? Along California’s coast, strong swells can churn up naturally occurring offshore oil seeps. Pacific Wildlife Care works closely with the Oiled Wildlife Care Network to monitor oiled wildlife admitted to our clinic. Samples are collected from affected animals and analyzed to determine the source of the oil. Oil has a chemical “fingerprint,” which can be compared to known samples to help determine whether the oil came from a natural seep or human-caused spill.
Both grebes received specialized treatment, including stabilization and a wash to remove the oil (don’t try this at home!). After washing, the birds spent time cycling between pools and drying areas while preening and realigning their feather structure needed for waterproofing.
After about two weeks in care, both Western Grebes passed their waterproofing tests and were successfully released back to the wild 💛
