There have been a ton of little birds flying around my house the past week or two and I just noticed they are building nests on the side of my house. I don't really mind, although the birds flying so close to the windows is driving my cats nuts, I just wanted to make sure its not somehow bad for my house. Also, does anyone happen to know what type of birds make these nests? I would take a picture of the birds, but they fly really fast and I never see them just sitting around.
The nest in the first pic isn't finished yet, so if it is bad for my house, I can get rid of it before it will dramatically affect them.
If you look close in the second picture you can see a birds head sticking out of the nest.
