It turns out that this is a significant stage in their nest building, and John Blakeman, our hawk expert from Ohio, sent me the following information:
Last week I asked John how the nest was looking, and about the pine greenery the hawks started bringing to the nest last week:
"The nest, and all of the activities there, are just perfect. The pair will use the nest once again. The evergreen sprigs are commonly brought to red-tail nests, for unknown reasons. But when they appear, it's a sign of profound commitment. We're on for a good year of hawk-watching. Nothing like it in all the world."
