Garden

Today I noticed a large mud-looking nest under the roof line of our two story house. At first I thought oh no, a bees nest, but realized it was not when I saw some movement inside and some tiny bits of something (not baby birds) falling from it. I googled nests but didn't see anything that looks like it. I wish I knew how to get a picture of it and put a link here. I haven't had time to just stand and watch it to see what comes out! Does anyone know what it might be? As I said, it is quite large.
