To update on this unexpected observation - the apparent smaller nestling has
not been seen for several days now. The larger fledglings seem to be in nearby
trees most of the time and the adults do not seem to be attending the nest any
more.
Thanks to everyone who offered feedback on the situation. Sorry I don't have a
happier ending to report.

Yes,
I have seen GHO's lay one egg every three days, and I have see them weight up
to and over a week or longer to lay a second or third egg.
It will be interesting to see what the parents do with the owlets when the
oldest owlets begin branching. But GHO's are very good parents for the most
part.

Hi Cobirders,
I've been watching a Great Horned Owl nest near my house in Superior. The
nestlings are getting pretty big and starting to move out of the nest and onto
nearby branches. However, a couple nights ago I thought I saw a small fluffy
white head sticking up among the much bigger other nestlings. And then today
someone sent me a photo which I think pretty clearly shows a young GHOW
nestling (totally downy, maybe 2 weeks old at most) in there.
Has anyone ever heard of such an age difference in GHOW nestlings? This is
clearly not just the usual asynchronous hatching. I thought perhaps the small
one could have been brought in as prey from another nest but it seemed to be
sitting up and alive. I didn't see anything like this in a quick google
search.
Thanks, Peter Ruprecht Superior
