Window strikes are one of the leading causes of human-related bird deaths. Birds that hit windows may appear to recover quickly, but many suffer from hidden injuries such as:

Head trauma (concussions)
Eye injuries
Internal damage

Even if a bird flies away, it may still die hours or days later

Outdated advice: “Leave the bird in an open box and see if it flies away.”

Current best practice: ALL window strike birds need help even if they seem okay.

What to do immediately if you heard, saw, or suspect a bird has collided with a window:

Safely contain the bird

Gently place a towel, sheet, or light cloth over the bird
Carefully transfer them into a ventilated container with air holes such as:
- A shoebox
- A cardboard box
- A large paper bag
Keep the box closed and place in a dark and quiet area.
For larger birds (like hawks or owls):
- Place a box or laundry basket over the bird if you are unsure how to handle them safely

Call Rockland Wildlife or a wildlife rehabilitator in your area

Do NOT wait to see if the bird “recovers”
Do NOT release the bird on your own
Do NOT handle more than necessary (this causes stress)
Do NOT give food or water

Report the window collision on DBird.org. Please report even if the bird flew away, died, or was picked up by a rehabilitator.
