Ace/Mrs. Ace left the nesting box a little late last evening (around 7:35 p.m.) then promptly returned for a little show.

   The drumming sounds on the Real Audio file here last about 20 seconds. Screech drumming.WMA

   Also got a great side view of a wing as Ace/Mrs. Ace flew off to the side and headed out for the night.

  I checked several times on the monitor but did not see the owl again until this morning.
