I heard a screech owl calling nearby Saturday at 4:45 a.m., but still no sign of an owl on the ScreechCam.
  Probably need colder weather, but you never know. So i am announcing another contest: By Friday e-mail me with the date when a screech owl will appear on the nest-box cam.
    Closest guess wins a copy of a soon-to-be-officially announced Celery Farm book.
