Re: [nfc-l] First migration of the season possible tonight in the mid-atlantic?

2011-09-12 Thread Bryan Guarente 
Ted and other interested parties,
I ran the HYSPLIT model (page to runyour own HYSPLIT) on your Sept 29, 2008 
date to see what the 6-hr backward trajectories would look like to get to your 
patch by 6AM.  The corresponding plots are here:

http://ready.arl.noaa.gov/hysplit-bin/trajresults.pl?jobidno=385220

You can take a look at those in Google Earth or Google Maps for best 
discrimination of the 6-hr backward trajectories.  If you zoom out and look at 
the general pattern, there must be a high pressure system rolling in from the 
northwest as the trajectories seem to fly these birds from Nebraska/South 
Dakota and back them into the Front Range.  I haven't checked the cloud cover 
or anything like that because you would likely know the information about that 
from in-situ observations.

For further maps, check these out (mean sea-level pressure):
http://virga.sfsu.edu/pub/composites/sathts_snd/0809/08092900_sathts_snd_alt.gif
http://virga.sfsu.edu/pub/composites/sathts_snd/0809/08092906_sathts_snd_alt.gif
http://virga.sfsu.edu/pub/composites/sathts_snd/0809/08092912_sathts_snd_alt.gif

There is a frontal passage at about 00 UTC (the first map), then the high 
pressure system rolls in over time.  The frontal passage seems to be the 
trigger in this case and in a lot of cases with a frontal passage, there is 
along-front flow like what is backing the birds into the Front Range of 
Colorado.  It is always hard to tell how the along-front flow will pan out as 
it depends on a lot of factors (location of the bird or birds on the front, 
depth of front, speed of frontal propagation to name a few).  


If you can pinpoint a better time for the movements that you wanted to target, 
we can be even more accurate, but for now this was my crack at it.

Re: [nfc-l] First migration of the season possible tonight in the mid-atlantic?

2011-09-10 Thread Allen T. Chartier 
Ted,

I'm glad that I'm not the only one who noticed the unusual phrase "first 
migration". From a birding and banding perspective here in southeastern 
Michigan, warblers and flycatchers (and some vireos) have been going strong for 
more than three weeks, and thrushes have been trickling through for a couple 
weeks, as expected. Some species, like Yellow Warbler, Warbling Vireo, 
Baltimore Oriole, and Bobolink are almost all gone from here, but we're getting 
close to peak for warblers and thrushes, with sparrows to start in a couple 
weeks.Definitely in the "middle of migration" here in Michigan...

  Hi, all.

  Thanks for the report.

  What fascinates me, from my Interior West perspective, is the phrase "first 
migration of the season possible tonight."

  Basically, we're done, finished, outta here, night-flight-wise, here in 
central Colorado. We had our biggest flights of the "fall" season a month ago. 
We were having heavier flights in mid-July than we are now. (ZERO flight calls 
the past week.)

  That said, we do get occasional light-to-moderate Sept. and Oct. and even 
early Nov. night flights in central Colorado. And rarely, they're heavy, as in 
the early morning of Sept. 29, 2008 (Bryan G., what was going on, 
winds-aloft-wise, that night??). But, basically, we're into the winter doldrums 
already!

  All best,
  Ted Floyd

Re: [nfc-l] First migration of the season possible tonight in the mid-atlantic?

2011-09-09 Thread David La Puma 
Tom Johnson sent out a text at ~5:30am this morning stating that he was
hearing many bobolink and thrush flight calls as both were dropping in
around Columbia St. in Cape May. Chase Scheifer posted on Facebook this
morning that he was hearing "hundreds of SWTH flight calls overhead". The
Dover, DE NEXRAD showed significant reflectivity even into the early
daylight hours this AM, and some reoriented flight was also evident
(something I rarely see on the radar, despite the morning flight phenomenon
common to Cape May in Fall)

unfortunately I'm stuck in the office today... good birding to all!

cheers

Hi all,

I'm in White Plains, NY and have been listening/recording for the past few
hours. Not much going on flight call-wise, perhaps two or three calls total!

[nfc-l] First migration of the season possible tonight in the mid-atlantic?

2011-09-08 Thread Andrew Albright 
Well it seems like it's been since spring since there was any night
flight.   The surface and lower level winds seem to be out of the
northeast and amazingly all the rain seems to be gone.  Maybe birds
are too water-logged to take off though?

However, I just listened outside and heard nothing and there's no
reliable radar to look at for this area (slightly northwest of
Philly).
