Saw your post on the Logan Cam site - 2 fledges, 1 intentional and 1 not. - So just one kiddie left on the ledge now? - Hope everyone is ok!
Chick still on the ledge seems to be willing to wait. Has been tucked up in the sun along the wall and occasionally goes to look out from the wall, but hasn't been up on the wall all morning. Sibling one is only about 8-10 feet below (or hopefully is still there) so they can still talk.
Fiona was on the west side nestbox a few minutes ago preening, so she seemed pretty calm about the whole fledging thing ...
