If you find a bird that has struck a window, take note of any obvious signs of injury.  Place the bird in a cardboard box with air holes and a secure lid. Make sure the box is just large enough for the bird to extend their wings (not too big, not too small).
Put the closed box in a safe, quiet and dark place.  Contact your local wildlife rehabilitation centre or call the BC SPCA Animal Helpline at 1-855-622-7722 for advice. Do not give the bird food or water.
Even if they become more active, do not let the bird go once you have contained them. Birds often have internal injuries after hitting a window, and will need help.
