After that she sang undersong. Dec. 23rd. Thrashers and wren. 9:00 A.M. On going to the glade, both thrashers and the little wren came for worms. In fact the wren was there when I entered. For a time all three were taking worms from my hands at the same time. Undersong was heard at various times during the day. Dec. 24th. Varied Thrushes.
