Their juvenile plumage didn't discourage the interloper from snapping at them, most likely because she wanted to court Webster, and they are his and Merriam's chicks, not hers. The girls may have begun migrating towards the coast at this point; we'll keep a lookout for them with the camera. (4/4)

Merriam's injury appears to be healing quite nicely.
The Powergrine Girls were last seen in the area several days ago and seemed timid to approach the Library after being chased away by the interloper for so long. (3/4)

With the interloper gone, our incumbent adults are much more relaxed in their behaviors. Webster has begun courting Merriam again. Our team jokingly notes that "it looks like he has some explaining to do based on her reactions to his overtures." (2/4)

Will this new female stick around?
-Uncertain, but she has already been spotted doing pair bonding activities with Webster. Falcons mate for life, but do not mourn; when a partner passes away/is killed, falcons will find a new partner relatively quickly.
Please reach out with any questions. (7/7)

What does this mean for the fledglings?
-Since they are not the new female's offspring, she's already been spotted snapping at them a bit. Fortunately, they are old enough to fly and hunt for themselves, and they will be moving out soon anyways for their first-year migration. (6/7)

Additionally, at the time of the injury, she was still actively taking care of the dependent chicks; removing her from the nest site would have caused her and the chicks undue stress. (5/7)

The decision to leave her to heal on her own was made based on the fact that observations indicated no broken bones or bleeding/infection, and that it was just some sort of bad sprain. When we observed her on Banding Day, it was clear that her injury was definitely healing. (4/7)
