Birds took advantage of lockdowns by hanging out in the city, study finds

Citizen science data tracks battle of birds vs bacteria

 E-Mail ITHACA, N.Y. - House finches are locked in a deadly cycle of immunity and new strains of bacterial infection in battling an eye disease that halved their population when it first emerged 25 years ago, according to new research from the Cornell Lab of Ornithology. House finch eye disease causes red, swollen, watery or crusty eyes. Afflicted birds can recover, but may die because they cannot see well enough to find food or avoid predators. The latest analyses, based on the observations of Project FeederWatch participants from eight Northeast states, addresses the long-term impact of the disease on house finch populations and points to the role of the finch immune system in the bird vs. bacteria battle.

House finch population unlikely to recover from eye disease, say researchers

House finch population unlikely to recover from eye disease, say researchers Today 5:15 AM Facebook Share While the house finch remains one of the 10 most common backyard birds in the U.S., its population of millions has been cut in half by house finch eye disease over the past 25 years and likely will not recover. Researchers from the Cornell Lab of Ornithology came to that conclusion based on data compiled by Project FeederWatch participants in eight Northeastern states, including Pennsylvania. They outlined the bird vs. bacteria battle they found represented in that data in the Journal of Animal Ecology, where they pointed to the role of the finch immune system’s reaction to the disease, which causes red, swollen, watery or crusty eyes. Afflicted birds can recover but might die because they cannot see well enough to find food or avoid predators.
