Couldn't see anything with my angle but it was possible that she could have been feeding something or helping pip. I don't know.
When I left yesterday morning there was no bird in the nest whatsoever which is sort of rare and unusual for the time.
Must have been off hunting or stretching her wings.
I got a call from my neighbor in the midday that the male was on the nest and it looked like he was feeding something.
I raced home but everything looked static, same as the last two weeks. Same thing this morning.
The hatchlings could be there, they may be out of sight. All I can do is wait. These shots are handheld. I look forward to sharp pics of babies off the tripod.
