Bird sounds

I found this while looking for pictures of birds I see around here. It has high quality recordings of common birds. http://www.cevl.msu.edu/~sg1410/docs/combirdsound.htm

Thanks MB,
I have been very frustrated trying to learn the birdsongs. Thanks for the help!

That's a neat site! We live right on the range border for two types of chickadees: Carolina and Black-Capped. The songs are the best way we could see which ones we have. What's funny is, we also have learned that the Carolina and Black-Capped are similar enough to one another they even interbreed -- and their proginy have a hybrid song borrowing from both sides' characteristics!
