After a great day of birding with friends in Michigan this past May, it was dinner time. It was also on the cold side. Aware of the constant risk of Covid, I suggested we dine outdoors on the patio at Mr. Jack’ss (and, yes, the two s’s are correct), the local eatery, familiar to me from previous trips. My companions were reluctant, preferring the warmer inside and accepting the Covid risk. That was until I pointed out that this was the best location in Tawas City to observe Chimney Swifts (Chaetura pelagica). We ate on the patio and the swifts were active, wonderful dinner companions. Which brings us to Roger Tory Peterson.
