hi folks,

I am doing a lot of point counts these days and reminded
of how variable the Yellow-rumped Warbler songs are, including:

a. trills (or "warbles") that, at the end, drop in pitch and speed up (as
if they run out of steam before finishing)
b. trills that ascend in pitch at the very end
c. trills that are two-toned; starting off one one pitch then switching
to a lower second pitch (similar in structure to a Nashville or Wilson's
Warbler)
 d. uniform trills with no distinct ending (reminiscent of one of the
American Redstart song types)
and others...

Some of these are highlighted in the Sibley iphone/ipod app (and I'm sure
on Dendroica as well):

a."Myrtle songs #1_NY" and "Myrtle songs #3_NY"
b. end of "Myrtle songs #1_NY"
c. "Myrtle songs #2_NY"
d. "Myrtle songs #4_AK"

I have heard all of these variations in the past month and have had to
track a couple down to verify they weren't early Redstarts, Nashvilles or
Wilson's (Wilson's-es?).
During migration period, sometimes even more so than song structure
and habitat, the pitch and timbre of their voice seem, to me, to be
the most reliable cues.

happy listening,
James.
