I found this dead bird on the ground in front of my house when I went out to take my walk yesterday. Right next to it was the smaller bird. I believe that the larger bird is a Merlin and the smaller one is a juvenile Blue Jay. The Merlin was right in the position you see here, as if still in flight. My house has very large windows. It appears that the Merlin had just caught his lunch and was flying to some safe spot to eat it when he flew into a window. There were a few small feathers stuck to the window above so I am fairly sure this is what happened.
Merlin's are small falcons, about 10 inches tall with a wing span of 24 inches. They do not live here in Western Massachusetts, so I assume this bird was migrating South from Canada, its summer home. It eats primarily small birds. It likes forests with open areas (precisely the type of spot I live in).
I called a taxidermist to see if he could help me preserve this bird. He is so beautiful and no injury is evident. I have never used the services of a taxidermist before. He is not sure if we will be able to preserve the bird because the State of Massachusetts has rules about what animals a taxidermist can preserve. A falcon may be out of the question. I will know more by the end of the week I think.
