There are two bits of news tonight. First, we believe there are now three eggs. The last picture in the group shows that most convincingly, although it could be just a shadow of something else.
The second news is that Mr. Owl has started feeding his mate, and she appears to be in 24x7 incubation mode. She left only once Wednesday morning, for an hour from 5:52 to 7:06 am She was in the box all day, never going up into the entranceway, except to leave for 25 minutes from 8:19 to 8:45 pm. She has been in the box all evening so far, the first pre-midnight incubation session. Mr. Owl was very diligent, feeding her 5 times in 25 minutes, between 9:05 and 9:30. It appeared to be small items like insects, as we only once got a glimpse of anything much in her bill. However, whatever cache of food he had discovered dried up, as he only came back for one more feeding, this between 11:00 and midnight.
Stay tuned. Hopefully we'll get a better look at the eggs when she leaves for her morning outing.
