Flyer Approved!
A 5 week old flying squirrel came running on our porch screaming for its little life. Our kitty’s were about to get it:(. After no luck of finding someone to take it, I found the goats milk substitute and I was able to feed that somewhat fine but overnight shipped this fox valley 20/50 along with picky blocks. Just from the first feed on fox valley I noticed a very positive change in the flying squirrels food drive! I was having no luck with solid food at all until I gave a small piece of picky block. Instantly nosed and ate it up. Very happy with the results I’m getting from this food. Excited to weigh the little one again and see the progress!

They like it!
Wasn’t sure what to expect - had read a lot of reviews about what to feed squirrels & everything said to feed blocks but that squirrels don’t really want them/like them. This was the first block we tried and both squirrels loved them. Would recommend

Life Saving!
Someone brought us a couple of baby squirrels and some goat replacement formula to feed them. Both squirrels had diarrhea and one was getting very sick/dehydrated. We bought the Wombarro formula & had it rush delivered. The formula literally saved their lives. Both of them took to it immediately, the diarrhea cleared up quickly and both of them started thriving.
The formula came in quick and in good condition. Very happy customer & squirrels! 100% recommend

Squirrel blocks were a hit!
My foster squirrel babies love the Henry’s Healthy blocks! They won’t touch other brands of rodent blocks, but go right for the Henry’s blocks. Henry’s does cost quite a bit more than other rodent blocks, but you get what you pay for. And I can feel secure knowing that they’re getting the proper nutrients from Henry’s to grow up healthy.

Peanut Stix - Treats for Squirrels, Flyers, Rats and Mice
If you’ve ever stopped to watch a bird glide across the sky or felt a moment of quiet awe when a deer stepped out from the tree line, you’ve enjoyed the beauty of wildlife that shares our world. However, many of the animals we admire face unseen threats every day, from vehicles and windows to pollution and extreme weather conditions. That’s where wildlife rehabilitators come in.
These dedicated individuals form the invisible safety net that keeps countless animals alive. Their work is a blend of science, compassion, and grit, unfolding behind the scenes in quiet exam rooms, outdoor flight aviaries, soft-release habitats, and emergency rescue calls. This guide takes you inside that world, offering a warm and educational look at what rehabilitators do, why their work matters, and how they help restore the balance between people and nature.
The Heart of the Work: What Wildlife Rehabilitators Do ❤️
Wildlife rehabilitators provide life-saving care to sick, injured, and orphaned native wildlife with one mission: return each animal to the wild, fully capable of surviving on its own.
Their work spans a range of disciplines, including emergency medicine, species-specific nutrition, and behavioral conditioning. One moment, they might be stabilizing a stunned songbird who struck a window; the next, caring for a litter of orphaned squirrels found after a storm.
They also frequently treat turtles with fractured shell injuries that require delicate, specialized medical stabilization. Or seabirds weakened by oil exposure, exhaustion, or fishing gear entanglement. Every case strengthens their understanding of the complex ways human activity affects wildlife.
How Wildlife Rehabilitation Became a Profession 📜
For most of human history, caring for wildlife was an informal practice: neighbors helping a fallen nestling or farmers tending to an injured owl. That compassion still forms the heart of rehabilitation, but over time, it has become clear that wildlife needs more than good intentions.
As scientific awareness grew, governments enacted conservation laws, such as the Migratory Bird Treaty Act and the Endangered Species Act, making it illegal to possess or treat protected wildlife without proper training. These laws reshaped the public's understanding of what wildlife care entails.
At the same time, veterinary medicine advanced dramatically. Diagnostics, such as X-rays, and safer anesthesia made treating complex injuries possible. Public awareness campaigns highlighted threats like habitat loss, pollution, and window strikes. Volunteer networks formed, allowing rehabilitators to reach more animals faster than ever before.
Today, wildlife rehabilitation is recognized as a vital branch of wildlife conservation, combining clinical knowledge, ecological principles, and humane ethics.
Inside the Day-to-Day: What Rehabilitators Do 🔍
The First Step: Intake and Assessment 📝
When an animal first arrives, it may be cold, dehydrated, in shock, or disoriented. Rehabilitators must assess their condition quickly and gently, examining posture, responsiveness, hydration, breathing patterns, and possible fractures or wounds. This early assessment often determines whether the animal survives the crucial first 24 hours.
Medical Treatment and Stabilization 🩺
Wildlife rehabilitators perform a wide range of medically necessary tasks, often under the supervision of veterinarians. They clean wounds, stabilize fractures, administer antibiotics or pain medication, and deliver fluids to reverse dehydration. They must also monitor for internal bleeding, parasite infections, or neurological trauma—conditions that many species instinctively hide. In cases like shell fractures in turtles, treatment is meticulous; shells are living tissue, so even hairline cracks require stabilization to prevent infection and allow regrowth.
Nutrition and Species-Specific Feeding 🥬
Providing food for wildlife is a science of its own. Baby songbirds may require feedings every 15–30 minutes from sunrise to sunset, each meal tailored to their species’ natural diet. Orphaned mammals need specialized formulas to avoid fatal digestive issues. Herbivores require access to fresh browse that mimics their natural diet in the wild. For raptors and carnivores, whole-prey diets help maintain muscle development and hunting behaviors essential for survival after release.
Behavioral Conditioning and Wilding Up 🌱
Healing physically is only half the journey. Animals must either obtain or relearn the instincts that keep them alive, including hunting, climbing, foraging, flying, nesting, and avoiding predators. Rehabilitators observe their behaviors closely. Birds practice building flight stamina in long aviaries. Mammals learn to find food hidden around their enclosures. Reptiles acclimate to temperature gradients that mimic their natural environment. Keeping animals wild and maintaining their instinctive caution and natural responses are essential. Human habituation can make release impossible.
The Moment Everyone Waits For: Release 🔚
When an animal can function independently, find food on its own, and navigate its environment with confidence, it’s ready to go home. Releases often take place at dawn or dusk when conditions are safer and temperatures are milder. Watching a once-fragile animal fly, leap, or swim back into its habitat is the moment that fuels every rehabilitator’s passion.
The Skills Behind the Heart: What It Takes to Do The Work 💡
Medical Knowledge Rooted in Wildlife Biology
Rehabilitators develop a deep understanding of wildlife physiology, including how shock presents differently in birds versus mammals, how to detect dehydration from changes in feather or skin condition, and when an injury requires urgent veterinary care. They learn to recognize subtle symptoms that most people might miss.
Precise Handling and Physical Skill 🏋️
Handling wildlife requires controlled strength and practiced technique. A hawk’s talons can cause serious injury if not properly restrained. A panicked rabbit can break its own bones if held incorrectly. A small songbird’s bones are so delicate that even a slight misalignment of the fingers can cause harm. Rehabilitators must move with confidence, gentleness, and calm.
Emotional Strength in the Face of Uncertainty 💛
Rehabilitation is emotionally demanding. Not every animal survives its injuries, and many cases are heartbreaking. Baby season brings overwhelming numbers of orphaned animals needing constant care. Even the joyful moments, like release, are tinged with bittersweet hope. Yet rehabilitators stay committed because each success story restores a piece of the natural world.
The Different Specialties Within Wildlife Rehabilitation 🧑🔬
Avian Rehabilitation: Avian specialists care for songbirds, raptors, waterfowl, seabirds, and more. They understand feather condition, flight muscle development, waterproofing, and the dangers of imprinting.
Mammal Rehabilitation: These rehabilitators manage everything from neonatal squirrels to fox kits. Many mammals imprint easily, so rehabilitators must remain hands-off while still providing round-the-clock care, including feeding and medical attention.
Reptile and Amphibian Rehabilitation: Reptiles and amphibians rely on exact environmental conditions. Healing is impossible without proper humidity, temperature gradients, and UVB lighting. Specialists must understand these environmental requirements as thoroughly as they do medical ones.
Marine Wildlife Rehabilitation: Marine rehab is physically and technically demanding. Specialists treat buoyancy issues in seabirds, shell infections in sea turtles, and weakness from cold-stunning events. They maintain aquatic pools, monitor salt balance, and treat injuries from pollution or fishing gear.
Licensing and Certification Standards 📄
Because wildlife is legally protected, rehabilitators must hold state, provincial, or federal permits depending on the species they treat. This process includes coursework, facility inspections, mentorship hours, and continuing education. Rehabilitators must maintain meticulous records, adhere to biosecurity protocols, and meet the humane care standards outlined by governing agencies.
Inside a Wildlife Rehabilitation Center 🏥
Intake and Triage Rooms: Quiet spaces where animals are examined and stabilized. Lighting is subdued to reduce stress, and equipment is kept readily available for emergency care.
Critical Care Units: These units resemble small hospitals. They include incubators for infants or hypothermic animals, oxygen chambers for those with respiratory distress, and isolation areas for contagious patients.
Specialized Enclosures: Large flight cages help birds rebuild muscle and coordination. Soft-release pens provide mammals with space to exhibit natural behaviors. Aquatic pools allow seabirds and turtles to regain waterproofing and swim strength.
Outdoor Conditioning Areas: Animals nearing release are moved into more natural environments, where rehabilitators can observe how they navigate the terrain, find food, avoid threats, and interact with others of their species.
Common Wildlife Patients and Why They Arrive 🐾
Songbirds: Often collide with windows due to reflections that mimic the sky or vegetation. Migratory birds are especially vulnerable.
Raptors (Owls, Hawks, Eagles): Frequently hit by cars while hunting roadside rodents or suffering injuries from barbed wire or power lines.
Small Mammals (Rabbits, Squirrels, Raccoons): Commonly orphaned during landscaping, tree trimming, or construction, when nests are accidentally disturbed.
Turtles and Tortoises: Often struck by cars or injured by lawn equipment. Their shells contain nerves and blood vessels, making these injuries both painful and medically complex.
Waterfowl and Shorebirds: Regularly entangled in fishing line, hooked by discarded tackle, or exposed to pollutants in waterways.
Why Animals Need Rehabilitation 🔎
Human activity is the leading cause of wildlife injury worldwide. Vehicle collisions account for thousands of wildlife emergencies each year. Window strikes kill or injure up to a billion birds annually. Outdoor cats and dogs pose significant threats to fledglings and young mammals, especially during the spring and summer months.
Rodenticide Poisoning ⚠️
Another deeply concerning and increasingly common reason animals enter rehabilitation is rodenticide poisoning. Modern rodenticides don’t just affect rodents; they move up the food chain in dangerous ways. Raptors such as owls, hawks, and eagles are especially susceptible because they rely heavily on rodents for food. When they consume poisoned prey, the toxins accumulate in their systems, leading to internal bleeding, neurological issues, or collapse.
Other species, including foxes, coyotes, bobcats, raccoons, skunks, and even scavenging birds, are also at risk. By the time these animals reach rehabilitators, they may be weak, disoriented, or already suffering from organ damage. Treatment is intensive and not consistently successful. Rodenticide poisoning is entirely preventable, making education about safer pest control practices vital for protecting wildlife.
Habitat Loss and Environmental Stressors 🌪️
Urban development, deforestation, and construction projects destroy or disrupt nests, den sites, and essential food sources, thereby harming wildlife. Extreme weather events, often intensified by climate change, result in displaced, injured, or orphaned wildlife following storms, floods, or heatwaves.
Pollution and Human Debris 🛠️
Plastics, fishing line, netting, and other pollutants cause entanglement, ingestion injuries, and poisoning. Oil spills and contaminated waterways have a significant impact on marine birds and mammals, necessitating specialized rehabilitation.
Rehabilitation not only saves individual animals, but it also helps mitigate the cumulative impact of human activities on wildlife populations.

The Impact of Wildlife Rehabilitation 🌎
Every successful release contributes to the health of ecosystems. Birds play a crucial role in controlling insect populations, dispersing seeds, and maintaining ecological balance. Mammals play roles in pollination, soil aeration, and forest regeneration. Reptiles and amphibians provide natural pest control. Marine species regulate ocean ecosystems and nutrient cycles.
Wildlife rehabilitators protect these essential processes one patient at a time, ensuring that the natural world remains vibrant, resilient, and connected.
