Don't birds sleep too! especially when its pitch black outside!
So I'm laying in bed last night and I hear this chirping. Loud chirping and its 1:30a.m!!!! what??? I heard it a few nights back too, but didn't bother me too bad. I couldn't block it out! So I came downstairs to see if maybe they were all at the feeder or something, nope, couldn't see them. What the heck! where were they? I couldn't block them out, so I went to sleep last night with my MP3 player. Thanks the soundtrack of HSM (High School Musical to all you who don't know), I was able to fall asleep soundly.
Birds need a bedtime!
