Window collisions are a leading cause of bird deaths with an estimated one BILLION birds dying every year. The majority of these deaths occur in the fall, during the annual migration south to wintering grounds.
What makes windows so deadly for birds in the fall? A window collision is just as deadly in any other season. But two main factors contribute to the higher death toll during fall migration.
- More birds. Birds spend the summer raising broods and the overall bird population is highest in the fall. Many species of songbirds raise multiple batches of chicks over the summer months. More birds = more collisions.
- Inexperienced birds. This year’s crop of chicks is migrating for the first time and they don’t have the same experience as adult birds in finding the right places to stop for rest or food or water. They’re exhausted and hungry and a reflected tree looks very inviting. Bird mortality due to natural causes is also higher in birds on their first migration.
