Editor’s Note: The juvenile double-crested cormorant 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.
The Clinic for the Rehabilitation of Wildlife (CROW) is currently caring for a snowy plover (Anarhynchus nivosus). This tiny shorebird (patient 26-57) was found on Sanibel with what initially appeared to the rescuer as a broken wing.
Once the plover was transported to CROW, the veterinarians conducted an examination and found no fractures or injuries. However, the plover was exhibiting symptoms commonly associated with a toxin exposure, including neurological signs that caused the plover to appear as if it had an injured wing.
CROW regularly admits patients with neurological deficits, often caused by harmful algal blooms, such as red tides. The algae associated with red tide produce toxins (brevetoxins) which bioaccumulate in the tissues of fish, invertebrates, and their predators. The toxin interferes with neurological processes, often leading to death if left untreated. The toxin can move up the food chain, affecting a wide range of species, including sea turtles, marine mammals, birds, and more.
CROW’s hospital team has been providing round-the-clock care for this patient. After just 3 days in care, the plover regained the ability to stand, a great milestone in its recovery.
Snowy plovers are a tiny, sand-colored shorebird that forages high on the shoreline. They feed primarily on invertebrates and make their nests right on the beaches. However, these nests are often inconspicuous, and face threats from increasing beachfront development – beachgoers unintentionally step on eggs or crush them with vehicles. According to the 2025 State of the Birds report, the snowy plover population has decreased by 50% over the last 50 years.
Beachgoers play a vital role in supporting snowy plovers and other wildlife by respecting posted signs, avoiding nesting areas, and leashing dogs to prevent accidental harm to birds and their eggs. If you spot an animal in need of help, report it to CROW immediately. Even small actions, such as properly disposing of trash and volunteering for beach cleanups, can help create a safer environment for these remarkable birds.
