This video segment adapted from Rx for Survival follows Tracey McNamara, lead pathologist at the Bronx Zoo, and her work to explain why crows in New York City were literally falling dead from the sky during one summer. McNamara traced the cause of the mystery illness to a mosquito-borne virus, and then suggested a possible link between the animal illness and an ongoing outbreak of human illness. In the end, McNamara was proven correct: it turned out that the same virus—West Nile virus—was infecting both birds and humans. A background essay, discussion questions, and standards correlations are also provided.
