I was wrong about two things in my post yesterday, that early nest activity was boring and that we would have no sun until mid-week. The hawks, young and old were very active at Riverside and there was sun all afternoon.
The adult male brought lots of twigs with leaves to line the nest and stayed close to the nest for most of the afternoon. The female rearranged lots of twigs and moved some dead prey around. She also removed some of the well eaten prey.
