It happens far too often, a bird is fooled into thinking it can fly through a window and instead, the bird collides with it. We saw a solution in Costa Rica that we have adapted to two of our windows. It has helped to reduce the incidence greatly. Dan drilled holes in PVC pipe and threaded simple twine threaded through it, then hung the barrier on the outside of the window. The holes must be spaced 4 to 4 !/2" apart at most for it be effective.
Recently, we did have a bird hit a narrow window that was not protected. Fortunately, the bird did recover! Here's the story.
A Blue Jay had made an alarm call and a Black-throated Green Warbler took off, colliding with the window. I turned to see it and took a quick photo.
Dan heard the bird hit, too and brought out a container lined with a towel. (We have also used a shoebox as is sometimes recommended.) I held the bird in my cupped hands for a few minutes to keep it warm and then placed it in the container to rest. It was stunned and took about 20 minutes before it hopped up to the edge when it was ready and flew deep into a nearby dogwood, where I lost sight of it. What a relief it is to see a bird recover after this happens.
We are very fortunate in the St. Louis area to have the organization Wild Bird Rehabilitation to help our native birds. This is their website: http://wildbirdrehab.org
