Over 22K Birds To Fly Over Cincinnati Tonight, Here's Why

A day after more than three million birds crossed Ohio overnight Monday, at least 22 thousand per kilometer will fly across Cincinnati on Tuesday and Wednesday, The Cornell Lab of Ornithology’s BirdCast migration dashboard shows. The platform, that predicts regional nocturnal bird migration, further adds that the migration will continue on Thursday with less than 8000 birds on the move.

The tracker cites weather data and historic migration to predict the number of birds per kilometer across a region. It generally issues a 'high alert' when more than 22,000 migrating birds are expected.

"The BirdCast model predicts large numbers of birds will be on the move through this region tonight. You may observe their movements birding and listening by day and night. Remember that high intensity nocturnal migration may not necessarily mean an excellent day of birding; rather it means that large numbers of birds are migrating or predicted to migrate at night!" the alert reads. It further adds that residents should turn off all non-essential lighting from 11:00 PM until 6:00 AM to help these birds fly with ease.

"Bright lights attract and disorient nocturnally migrating birds, potentially causing fatal collisions with buildings or exposure to additional day time hazards."

These birds migrate to find better places to live as seasons change. They search for food, nesting and more daylight hours. In the spring, birds in the Northern Hemisphere migrate north to take advantage of more insects, plants, and nesting locations. In the winter, they migrate south to find food sources and milder climates.
