|American Robins from the beginning of Nov.|
I can't even count the number of dead or injured birds we have found around work that were victims of window strikes. If I were to estimate over the last 4 years... I'd guess around 300. What amazes me is not the number but the fact that those are only the ones I've seen. When I think of all the other building in the world and all the other windows, the estimates conservationist make seem beyond real and more like an understatement.

Here the abundance of window strikes is without a doubt Dark-eyed Juncos. These small gray-brown sparrows breed across Canada and into the northern US, including some higher altitude areas farther south. During the winter they migrate south as far as parts of Mexico to forage for food and survive before heading north again. There are quite a number of forms of Dark-eyed Junco as would be expected from the large distribution of the species. To go into any more details about their behavior would require discussing separate forms. Instead, I just also mention that they are NOT the only birds that have been killed.

|Me illustrating the final product, it doesn't stop the strikes|
but it does reduce them.
