Avian Rehabilitation and Conservation
Bird Rescue and Rehabilitation
As the seasons change, so too do the needs of our feathered friends. While summertime often brings an influx of orphaned chicks requiring dedicated human foster parents, the winter months present a different set of challenges for avian caretakers. ”In the winter, there are no healthy orphans. Every bird that comes in is a medical case,” explains Avian Care Director Dr. Karen Higgs of Bird TLC in Alaska.
At the heart of avian rehabilitation lies a delicate balance – restoring the health and independence of these precious creatures so they can be released back into their natural habitat. This mission is at the core of organizations like the Rogers Wildlife Rehabilitation Center in Texas, which has provided medical treatment and care for over 120,000 birds in the past 25 years. Many arrive with life-threatening injuries caused by animal attacks, vehicle strikes, natural disasters, or even human cruelty.
Seasonal Bird Populations
The winter months bring a unique set of patients to rehabilitation centers. Migratory birds like the Northern Hawk Owl, one of only two diurnal owl species in the world, may find themselves in peril as they journey to their wintering grounds. Struck by a car along the coastal Seward Highway in Alaska, this remarkable raptor was rescued and transferred to Bird TLC for rehabilitation.
Rehabilitators must not only address the bird’s physical injuries but also consider the complex factors of its natural habitat and migratory patterns. “Since this is a hawk owl, he likes the boreal forest habitat, which is black spruce mixed with some aspen and birch. Seward is a rainforest,” explains Tasha DiMarzio, a waterfowl biologist from the Alaska Department of Fish and Game. Carefully selecting the release site to match the bird’s preferences is crucial for its successful reintroduction.
Rehabilitation Techniques
The road to recovery for injured and orphaned birds often begins with specialized medical care. In the case of the Northern Hawk Owl, X-rays revealed a fracture in the wrist-like bone of its right wing. Prompt intervention, including the use of a splint to repair the break, allowed the bone to heal properly within just 7-10 days – a testament to the remarkable healing abilities of avian species.
Physical therapy under anesthesia helps strengthen the bird’s muscles, while natural movement in an enclosure further builds its flying fitness. Before release, a final checkup ensures the patient has regained its full range of motion and overall health. “Except for a naughty finger nibble, the patient cooperated,” notes Dr. Higgs, highlighting the tolerant nature that makes Northern Hawk Owls vulnerable to poaching and other threats.
Release and Reintroduction
Releasing a rehabilitated bird back into the wild is a moment of triumph, but it requires careful consideration. Rehabilitators aim to return birds to the area where they were found, as this familiar territory offers the best chance for survival. However, in cases where the original location is unclear, as with the Northern Hawk Owl rescued along a highway, experts must carefully evaluate alternative release sites.
Factors such as habitat suitability, weather conditions, and the bird’s natural behaviors all play a role in the decision-making process. For the Northern Hawk Owl, Tasha DiMarzio scouted locations between Seward and Anchorage, balancing the region of origin with a habitat where the owl would thrive. As the sun began to set on the first day of December, the owl was released into its new landscape, carrying the hopes of the dedicated rehabilitation team.
