Re: [nfc-l] Night Flight - Battle Ground, WA

2011-10-07 Thread Jim Danzenbaker 
Hi Jay and NFCers,

Like Jay, I was socked in with rain this morning - very dismal throughout
the day although I saw birds slowly emerge out of the gloomy overcast.
Surprisingly, I didn't here a single peep, zeep, chip, whzu, or blurp
overnight which I thought was strange.  Every night I hear something flying
over...

Jay's synopsis and description of Varied Thrush migration calls (nocturnal
and diurnal) are right on the money.  I usually hear them for about two
hours after dawn but hardly ever at night.  That's why hearing them early in
the morning (1 1/4 hours before daylight) of Oct 6 was so strange (they call
pre-dawn in Spring).  They were probably flying over and calling earlier
than that but I was asleep and I don't have any recording equipment.

All,

Cool description!

Varied Thrush doesn't appear to be on the oldbird CD. Can someone post
a night flight call clip?

Sincerely,
Andrew

Since Jim is undoubtedly enjoying a flood of migrants this morning 
after what has apparently been the heaviest migration night of the 
season, while I'm socked in with rain 25 miles south of him, I'll go 
ahead and respond

Varied Thrushes give a flight call very much like the lovely iconic 
song that reverberates through the PNW rainforests -- that ethereal 
combination of a whistle and a vibratory hum.  However, the call in 
flight is generally a shorter and throatier version of that 
vocalization, more of a guttural "whzu" than a long thin 
"whheee".  This call is also heard on the ground.  I've heard 
this call from birds in flight at night, at dawn, and after daylight. 
They seem to me to call more at dawn and after dawn than at night, 
but then that may simply be a function of when I'm most often 
listening.  Jim's more nocturnally active than I am, so I certainly 
trust his judgment on this.  Like Robins, Varied Thrushes continue 
their nocturnal migration for sometimes up to a few hours in the 
morning, so it is feasible to see them as they migrate over, 
occasionally calling.

I've never heard their Hermit-Thrush-like "chuck" or "tuk" call note 
used in flight.

Jim, any comments on the above?  I'm hoping that you've gotten a 
flood of birds over your yard last night and this morning and that 
the rain clears up a bit down my way so that I can partake, too.

I also add a hearty thanks to everyone sharing their experience of flight

[nfc-l] Night Flight - Battle Ground, WA

2011-10-06 Thread Jim Danzenbaker 
Nocturnal flight enthusiasts,

I live in Battle Ground, Washington which is 20 miles due north of Portland,
Oregon.  I've been listening for about 6 years - mostly Swainson's Thrushes
which can number in the thousands on some nights in September.  I was
listening from 5:45-7 this morning and had a good variety although not many
individuals:

Varied Thrush 21*
Hermit Thrush 1
Swainson's Thrush 3
*Zonotrichia* 1
Song Sparrow 1
Yellow-rumped Warbler 1
misc chips 8

* this is only the third time I've heard nocturnal migrant Varied Thrushes
and only single birds on the other two occasions.

Conditions were overcast with calm winds which was a big change from the
south winds and rainy conditions of the last several nights.
