I shockingly heard the song of the Tennessee Warbler this morning. The last Tennessee song I heard this year from the Mississippi River area this spring was on June 2. The bird was singing from the Honey Locust trees at the Minneapolis Parks fountain next to the ING building on Hennepin Avenue. I did not have my binoculars with me, but I usually bird by ear anyway. Maybe someone could head over there and confirm with a sighting.
