It was actually nice today, instead of super-dreary and rainy, like the weather predictions claimed. So I left early and walked around the pond for almost an hour before brunch. It was great!
Turns out there were two of them! It struck me more as pair bonding than as a dispute, but of course I don't really know.
No herons or egrets, several kinds of sparrows, no warblers, no kinglets. The hawk flyover really made the morning, that and the gorgeous weather! Now, off to meet the girls for brunch. :-)
