Humming Birds ( )

I recorded this with a yamaha pocketrak that i taped to the feeder and enhanced the vol. With sony sound forge. It was fun to watch their reaction to the recorder but they eventually figured out it was harmless. Hunger overcomes fear every time. :o) here and there you can hear our tv in the background as i forgot to mute it. Please comment on what you may use it for. Thanks. :o).
