Number: 200

200 were tagged on Saturday at the Springfield Botanical Center and most of the tagged ones had headed south by Sunday. Migrants continued to arrive in the gardens (There is a video clip in the album linked below). We drove A 5-mile EW transect on Grand Avenue at noon on Sunday and counted 30 monarchs crossing in 10 minutes. We could see them up to about 60 yards away, so we estimate that 180 butterflies per hour were crossing each 60 yards of that 5 miles. For the whole 5 miles, ([5*1760]/60)*180 = 26,400 monarchs per hour passing Grand Avenue! Photos from the Roston Native Butterfly House at https://photos.app.goo.gl/TwWezPfjVhohpCln1
