The first egg, which never hatched, is still on the nest. Sometimes, Rosie carefully rolls it and sits on it.
There are occasional intruders but Rosie and Richie ably defend the nest. One visitor seemed to excite them but it turned out another osprey was flying around as well. The egret was not a threat and was let be.

Rosie feels comfortable leaving the chicks alone on the nest now, but she stays nearby, ready to step in when necessary. Richie, too, though he may not be seen by the cam, is usually nearby and shows up quickly when an intruder approaches.
