Does anyone have their ears on out west? I still don't have my
night-recorder set up (old laptop with windows Vista on it. Lousy system!).
Haven't seen many stopover birds yet.

The night flight overnight last night (9/15-9/16) was amazing to hear. Near
constant flight calls. Wave after wave. Species composition or, at least,
prevalence changed throughout the night.
Early in the evening (I started listening and recording at 8pm), there was a
heavy movement of Rose-breasted Grosbeaks, with various warbler flight calls
throughout. There were also occasional Green Heron and Swainson's Thrush
flight notes.
By mid-night flight, there were very frequent Swainson's Thrush and
Gray-cheeked Thrush calls, as well as regular Chestnut-sided Warbler and
Black-throated Blue Warbler flight calls. Occasional American Redstart,
Ovenbird, and a handful of White-throated Sparrows.
What was also interesting was this: I started out recording with my
Evans-style flowerpot (with the knowles element), acquiring using Raven Pro
on my Macbook Pro. Around 2am, I awoke to an acoustic spectacle that I felt
needed to be record with a slightly higher fidelity setup. I place two Rode
microphones out on the rooftop and began recording simultaneously with my
Zoom H4n recorder. With the latter setup, I was careful to arrange the
microphones (and my earbud headphones) such that my right ear was listening
to the ENE and my left ear was listening to the WNW. Interestingly, nearly
all thrushes heard calling were apparently moving in the distance to the
ENE. I did not notice many at all that were as loud heard calling out of the
WNW. This makes me wonder if it is at all possible that most of the birds I
heard were moving down the valley well to my East.
In any case, this was a very memorable night flight.
Attached is a Dickcissel that called at about 9:07 last night (I'm browsing
through sounds right now - Flowerpot recording).
