West Nile virus may no longer be a death sentence to crows. In a new study from the College of Veterinary Medicine, wildlife experts describe successfully treating and releasing five American crows infected with the deadly disease, These are the first known crows to survive West Nile virus.

The effects of lead poisoning can vary depending on exposure, but they’re often devastating. Cornell wildlife ecologist Dr. Krysten Schuler notes that lead impacts every system in the body and that while eagles have been carefully studied, it’s likely that other animals are affected by lead poisoning too.

Anticoagulant rodenticides continue to be used across the U.S. as a method for controlling pest rodent species. As a consequence, wild birds of prey are exposed to these toxicants by eating poisoned prey items.

This female snow goose came to the Janet L. Swanson Wildlife Hospital for lead toxicity. She couldn’t keep up with her flock on its migration north because she was too sick to fly. The Cornell team nursed her back to health and she was released back into the wild.

Raina Plowright, a world-renowned ecologist and epidemiologist who studies the mechanisms that drive the spillover of pathogens between species, has joined the College of Veterinary Medicine. Her transdisciplinary work demonstrates that preserving and restoring wildlife habitats can stop pathogen spillover by minimizing contact between infected wildlife and potentially susceptible livestock or human hosts.
