It was the full moon last night so my roommate wanted to see it in my scope and take some digiscope photographs.  While I was watching the moon with a 50x eyepeice on the balcony of my north Baltimore apartment (around 1:00 am), I noticed a lot of birds were flying by.  I had 1 Grackle, 1 Swallow species, a couple thrushes and a bunch of small warbler/sparrow type passerines.  There was about 1 bird per minute.  This would be an interesting way of measuring migration even if most aren't identifiable as to species.
