I rescued a bird inside the library today; the door was open. Apparently, blinded by the morning sun they fly into windows or closed doors and kill themselves. Can we place something on the glass to let them know they can’t fly through it?
They do make a glass door covering that looks clear from the inside, but opaque from the outside. It’s like a fine mesh that’s painted on the side that’s facing outward, but from inside the house, you barely notice it.
we put a decal of a predator bird on our windows, discourages them suckers real well.
I lived in a home with a bay window several years ago. About once every two weeks, we’d hear a Bonk. Most of the time, the bird managed to flutter away. In fact, we had a birdcage available to hold any that became stunned until they were ready to fly again. To solve the problem, we put some stained glass light catchers inside the window, and an extra bird feeder nearby on the outside. I don’t remember hearing any crashes after that. They either caught the reflections or diverted to the feeder.
Good luck!
Here’s the advice from Wildbirds.com and the Audubon Society on the problem.
I used to have a bird feeder on the deck and quickly realized the tiny thud was birds hitting the sliding glass door. Apparently they were too close to get up much speed and just needed a few moments rest before taking off again. Moving the feeder further into the yard seems to have resolved the problem entirely, of course, the big unbrella over the deck table might play a part in this, too.
The problem was that the hawks (probably just one) would swoop down and pick birds of the feeder. If the hawk scored a near miss, the bird would often take off and give the hawk a bad time tearing through small openings in the tree leaves and often into a dense rosebush where the hawk would not fit. I moved the feeder further into the yard where the hawk would not have a clear line of sight (before h’d just sit on the yard’s fence and take his time selecting lunch) and made a large chicken wire-like cage for the feeder. Spaces big enough for the songbirds and way too small for hawks. He went away.
Colibri’s Audubon Society site has a paragraph on hawks, too.
