I heard one NORTHERN WATERTHRUSH on Friday morning east of the Woodleton
Boardwalk in Sapsucker Woods. This waterthrush sounded like a typical
Northern Waterthrush -- not one with the "Woodleton accent" (dip in pitch in
the middle, then emphatic at the end -- very distinctive in 2001-2003, less
so in recent years). I've never noticed any different-sounding Northern
Waterthrushes anywhere else.
On a full circuit of the East Trail, I found no Hermit Thrushes.

About three or four years ago I found similar differences in songs of
Northern Waterthrushes. All in the same location, that is Sapsucker Woods on
the Dryden side of the trails.
Initially, I distinguished them by sound, then I recorded them and looked at
the sonograms. I was surprised that my ears, which in the previous years
could not distinguish between Northern Lousiana, but now could tell the
difference between the individual Northerns was amazing to me. Definitely
listening to more individuals helps!
