...falcons again this morning, between 8:00 & 9:30 wpg time, Trooper sat on the ledge for quite a while, watching (probably) Durand flying around, then Trooper got into the nestbox for some scraping & inspecting. Trooper then left for awhile, but Durand showed up, and also entered the nestbox - her inspection was a little more intense, she kept checking out the ceiling as well as the gravel. Of course, I am just assuming it was Trooper (no bling) and Durand (bling) - I don't know them well enough to id by sight, but it was nice to see them hanging around for so long...
