being treated for a parasitic infection and injuries resulting from a window collision Most of the Wild Bird Fund's patients are brought to the facility by members of the public, as well as by organizations like the
Animal Care Centers of NYC and the
NYC Department of Parks and Recreation. The hospital treats a wide range of bird species, as well as other small wildlife, though its most common patients are pigeons. The leading cause of injury is window collisions. New York City was built along the
Atlantic Flyway, a major migration path, and birds are confused by lights behind the windows or reflections of trees or sky, colliding with glass in large numbers, especially during spring and fall migration. The New York City
Audubon Society estimates the number of bird deaths by window collision in the city to be between 90,000 and 230,000 each year. Most crashes occur during fall by birds making their first migration. For recovered birds, the site of release is based in part on whether they are migrating, and in which direction. While many pigeons are released in nearby Central Park, birds migrating south might be released in
Prospect Park in Brooklyn, which allows a mostly clear path to the south as compared to Central Park and most other sites in Manhattan. The hospital employs an animal care staff of about 25 people, with assistance from 100 or more volunteers. It does not charge for services, relying largely on individual donations, as well as foundation grants and sponsorships. During the COVID-19 pandemic, with a larger number of people
birding and spending time in nature, the Wild Bird Fund saw an increase in the number of injured birds taken to the hospital, even while there was no evidence the number of overall injuries increased. == References ==
