Wilsonia pusilla.
Bethel, Maine.
copy 3
1903
June 4 // There was a Wilson's Black-cap singing freely and steadi-
ly among the alders by the brook (along the Grover Hill road). Its
song was we-we-we-we-we-we, all the notes on one key and without
special emphasis on any of them. I suppose the bird was a migrant.
