Phenology

Third Week of September

Swimming season winds down as lake water temperatures drop into the low 60s. Rafts of American coots arrive on southern Minnesota lakes. The attractive plum-like silver-white tops of Japanese silver grass are especially showy in low angle sunlight. Ruby-throated hummingbirds continue to visit southern Minnesota feeding stations but their numbers are decreasing; most will leave northern Minnesota by the 12th and the southern part of the state by the 25th. Keep at least one sugar water feeder up until the hummers have all left, possibly into October.

September 19, 2015: At Hawk Ridge in Duluth, 16,815 broad-winged hawks flew overhead on their way south.
