Fred and Tweeters,

I can't speak for other birders, but almost every Nashville Warbler I have
found in spring migration around Vancouver, BC (where they are about as rare
as they are in most of western WA) has been detected by song. I have
averaged about 1 or 2 Nashvilles per spring, going back to the late 1960s;
their status has changed little over the years.

Interestingly, Nashvilles are about as rare in fall migration as in spring
around Vancouver-- a total of about 3 to 6 records each migration season.
However, I have NEVER personally recorded one here in fall! I guess that's
because they don't sing in fall, and I am not good at picking out Nashvilles
visually from the other nondescript yellowish fall warblers. I've always
been far better at auditory identification of birds than visual
identification; my hearing is good, but my eyesight is not so good.

So I guess it varies among different birders just how they find these
migrant Nashvilles, but I think it would be fair to say that in spring, a
good percentage of them are picked out by song (which to me is quite
distinctive.)

The migrant Nashville warblers being found west of the Cascades
are they detected by song?
