The majority of bird species are migratory. Birds instinctively know it’s time to migrate when food supplies diminish and new nesting opportunities become necessary. Migration is both physically and mentally stressful for the birds. Besides navigating hundreds of miles, they need to search for food, avoid predators and risk bad weather conditions. Unfortunately, birds on a migratory route that includes a major city face another obstacle: skyscrapers.
Chicago is a major migratory route between Canada and the Northern United States and the Southern United States, Central America and South America. Usually migrating birds fly high in the sky at night and don’t rest until daybreak. It is in cloudy or windy conditions that the birds face the skyscraper hazard. The birds fly below the cloud cover and fly toward the lighting in the buildings. Windy conditions can blow them into structures.
For the last ten years a co-worker of mine has volunteered for the Chicago Bird Collision Monitors in downtown Chicago. Between 5 and 9am every Thursday during the spring and fall migration seasons he picks up migrating birds that have in advertently flown into skyscrapers. There are volunteers every day of the week during migration, which in fall extends from late August to Early November
On a busy day the bird patrol can collect up to 400 birds. Deceased birds are delivered to the Chicago Field Museum for research and become part of their collections. The injured birds end up at Willowbrook Wildlife Center where they are tended to by a veterinarian and eventually released in the nearby Forest Preserve to continue their plight.
