Subject: [NHBirds] Dawn & Dusk MIGRATION! (Goldfinches, swifts, hummingbirds, WW Scoters, Brant, etc.)
Jane and I had a great time this weekend.  We are now in  the peak of
migration and the birds are pouring into and passing through the State. 
We were out most of the weekend in the seacoast and managed 130 species
without any major effort or rarities except for an extraordinary
PROTHONOTARY WARBLER found by Andrew McTammany in Exeter yesterday.

My impression is that migration has been a bit slow along the coast due
to the weather.  There are still some early spring migrants lingering
today (R-C Kinglets, B-H Vireo, W-T Sparrows), and we're still lacking
several species including Pewee and Indigo Bunting.

But the raw, inclement weather from the previous week broke free and led
to a nice strong front with NW winds yesterday morning.  This resulted
in a nice flight of some spring migrants along the immediate coastline. 
Interestingly, there is a predictable pattern of dawn and dusk migration
at this time of year with this weather pattern.  Yesterday we managed to
capture both in the same day. Burning the Birding candle on both ends as
Jane says!

The following list is MIGRATING birds only.  Heading north along the
shoreline and passing through NH at Dawn and Dusk:

Comments:     3 hour morning migration following several days of
inclement weather and passage of front late the day before.  Brisk NW
winds for the entire period and blue skies.  Excellent flight of
goldfinches, swifts, and hummingbirds!  Very busy first hour. Lessening
later, but hummingbirds picked up later.
