Anyway, one owlet appears very healthy. Papa is providing a lot of food. Momma had 3 mice cached for the hatching on Thursday (did she know it was going to happen??). Papa brought her a 4th early in the evening. As any of you who have been watching during the day (especially Saturday) know, there are a lot of flies attracted to the nest box. Last night (Saturday/Sunday) Papa brought her one mouse early (11:28 p.m.) which she took but she sent him away when he arrived with more mice at 12:05 and again at 2:33. She must know that if she keeps too many, they will just attract more flies. She ate quite a bit herself and of course fed the young one throughout the night so the "cache" has been reduced a bit.
Here is a view of the owlet when she flew at 5:40 this morning (Sunday).
