Snowy Owl and Red Shouldered Hawk victims of collisions with glass.

The short answer is that every bird is susceptible to mistaking unprotected glass as clear, open sky.  As people are becoming more aware of the increasingly visible problem, reporting and sharing of information is helping us to see that any species that takes flight near a structure with reflective or transparent glass is at risk.  Pictures of owls, hawks, ducks, resident, migratory, and rare birds are emerging from concerned citizens who are looking for ways to prevent the disconcerting event from occurring again.
