Wood Thrush9/11/20161  Matsell is a good spot for migrating thrushes in the Fall, but Wood Thrush was a surprise. I rarely find them this time of year.
Wood Thrush6/6/20111PO-X Calling in concert with a Whip-poor-will, a beautiful pairing in the woods.
Wood Thrush6/27/20063  Three singing and/or scolding birds heard at dusk w/in a 100 yard stretch. I believe that this species is an annual nester at Matsell Bridge, although I've not documented this.
