Tom, all-
Call notes are also diagnostic for each species if they're actively
vocalizing. I've used this to ID the four or five empids I've had this fall
(along with appearance, of course). Like I said, I've been lucky (however, I
also ear bird too much, and likely have missed non-vocal empids). And
there's a lively discussion on ID-Frontiers about separating Willow from
Alder flycatcher by structure and appearance, although this (apparently -
it's not for me) takes a lot of experience. That all said, I too would be
surprised if every empid seen were vocalizing.
Andrea's point is a very good one - we should continue to be honest with our
reported observations, even if we think no one is looking. Because they are!
I for one wouldn't mind if eBIrd had some sort of behavioral tally as well
as age and sex categories, because it would be nice to remark upon whether
you heard a bird, what voc it used, etc. That might also add some level of
confidence in Alder/Willow IDs.
On a separate point, today I went to enter a Baypoll, and there's no slash
category for that one on the list that I can see (i.e.
Blackpoll/Bay-breasted Warbler). Not sure what's going on there. It went
into the warbler sp. category.
