Hi Night Flight enthusiasts,

Jim Danzenbaker here from Battle Ground, Clark County, Washington which is
located about 20 miles north of Portland, Oregon,

I was glad to hear a flood of nocturnal migrants flying over my house in
Battle Ground, Clark County this morning.  I estimated about 5 birds per
minute at 4:45am which built to about 15 birds per minute from 5:10am until
about 5:45am and then it dropped off completely after 6am.  Interestingly,
this coincided with the National Weather Service Radar from Portland which
showed lots of blue (presumed migrants) at that time which dropped off at
around 6:06am.  I estimated the following numbers:

Swainson's Thrush 475
Yellow Warbler 1
Orange-crowned Warbler (I think) 1

This flight was not unpredictable since the winds turned northwest yesterday
evening for the first time in several days and there was a fairly low cloud
deck. This morning, there wasn't even a hint of a breeze.   This is the
earliest that I've had a big flight.  It usually starts around August

Kep your eyes and ears skyward!
