Hello folks. I arrived home at 1:30am to quite a racket in a tree by the window to my apartment. I tried to spot the bird with a flashlight but was unable to do so. I was however, able to record it's song with my iPhone voice recorder. I was wondering if any of you guys could help me identify it. I made an MP3 of the song and attached it to this post (at least I think I did). I am guessing this is a common bird but I don't recall hearing anything like it. It makes several different sounds in the 35 seconds of the clip. Thanks for you time!
