This morning I walked up the road at Radnor Lake toward the Education
Center. Where the power lines cut through near the top of the hill I heard
the distinctive call notes of a Mourning Warbler several times. I saw
movement a couple feet off the ground in the tall weeds at the edge of the
road, and then it appeared in the open for a brief look before flying low
across the road to the other side. I never saw it again. It appeared to be
a first fall bird with yellow continuing from the throat all the way thru
the undertail coverts. It was plain olive above. This is the exact same
area where several of us saw a Mourning Warbler Sept. 7-8, 2015.
Judging by the records I have this would be about two weeks earlier than
the earliest date for the Nashville area. Terry Witt had one at Radnor on
Aug. 11, 2000.
