If you’re like me, you had a lot of neighbors return over the weekend, and they don’t appear to be self-quarantining. Weirdly upbeat in these difficult times, these newly arrived locals can be heard whistling cheerful tunes as they settle back in to their routines in yards and gardens. Many are even visiting crowded food establishments and communal baths of suspect sanitary status. Obviously I am talking about your local orioles, catbirds, and hummingbirds, and they got here not a minute too soon in these stir-crazy times.
