Feather Loss Leaves Barred Owl Grounded, Vulnerable

Editor’s Note: The Barred Owl is part of the CROW CAW (Case A Week) series, which tells the stories of the patients at the Clinic for the Rehabilitation of Wildlife on Sanibel Island, the dangers they face, and how we can help protect all of our wildlife. Read previous cases here.

An adult barred owl (patient 25-4155) is currently in care at CROW after being found limping down the middle of a road in Estero. A concerned rescuer safely contained the bird and brought it to the clinic for treatment.

On examination, CROW’s veterinary staff noted common issues such as dehydration and emaciation – but what stood out the most was the owl’s missing feathers. While the exact cause of the owl’s condition is unknown, it may have been attacked by a predator or experienced another type of trauma that caused the loss of many crucial flight feathers. The owl is very thin, likely because it hasn’t been able to fly and hunt effectively.

Despite its missing feathers, the owl is otherwise in good condition. CROW’s team is providing supportive care and analgesics while they monitor the patient’s recovery and feather regrowth.

Barred owls are a year-round resident here in Florida, and they are one of the most common owls in North America. They are listed as Least Concern on the IUCN Red List due to their adaptability to a variety of habitats and their extremely variable diet. In fact, their population and range have increased since 1966 – an unusual trend among birds.

Barred owls get their name from the distinctive brown and white pattern on their plumage. This nocturnal species can be recognized by its unique vocalization, which sounds like the English phrase, “Who cooks for you? Who cooks for you all?” Their most common predator is the aggressive great horned owl, but they also face threats from vehicle collisions and the loss of wooded habitats.
