(I do agree that 1, 2 and 4 are likely the same species, but I have
recordings of a Yellow-rump doing a similar high-slurred ending (which I
recorded on three successive days in Massachusetts, failing to see it
and believing it to be a Blackburnian, but finally seeing it on the last
day and visually it was a completely typical eastern Yellow-rump). They
are usually in about this right range, and of extremely variable timing.
So, I would give the probability for Dendroica fuscus less than 80%
because of this atypical voice range.)
I agree, the sounds are alike and I like a good constructive argument.
Not all Cerulean recordings are the same (not in my book anyway) I have
recordings that certainly don't end in a zhreeeeeeee and some that do!
Now just because there are more of one and less of another doesn't sway
my vote either! And getting all this from a 1 second sound byte
certainly makes me think there is room for error too. I have recorded
Blackburnians that I had thought were Yellow-rumped and have been in the
same situation like you, seeing the bird in the flesh!
I still go with Doug with his analysis on the strength of what I have
that sways me to the Blackburnian.
Incidentally, I have 4 recordings that I would like both of you
disbelievers to identify, I know the answers but I want you to show me
what you know and Marty, they are not Rails!
