Heavy migration last night

Heavy migration over the northeastern and mid-Atlantic US will mean lots of influx and replacement into our region. Here’s the radar from 7:00pm last night through 5:00am this morning.

While I had expected the winds to turn more northwesterly last night, it appears that they stuck closer to northerly. This is supported by the velocity image which shows most movement heading N->S across the region. Since migration was heavy and widespread, most fall migrant traps across the region should be seeing some new birds today. Cape May is still a good pick since the regional map shows a good movement of birds down the east coast from New England; while interior locations will be good today for both migrant songbirds as well as diurnal raptors.

Good Birding

  1. Duke was hopping this morning!

    BIG passerine flight driven by:

    Golden Crowned Kinglets- ~60
    R C Kinglets- ~20
    Palm Warblers- ~40

    White throats- ~40…first “wave”, we’ve had small groups for a few weeks already.
    Fields- lots. I lost count. We saw a lot at Cold Brook on Sunday too….I guess they peak early?
    Savannahs- lots. again I wasn’t counting
    White Crowned- 6
    Swamp- 2

    I thought for sure I’d see my first vesper today but no luck!

    diurnal migrants:
    flyovers: cooper’s hawk, harrier (1), broadwing
    hunting the fields: harriers (3), kestrels (6)

  2. ~7:25 to 8:40 at the Celery Farm: Nice morning. 7 warblers incl. Nashville, Parula, BT Blue (f), Blackpoll; my first of fall White-crowned (ad.) Chipping (2-rare at CF); RC King (4+); and Rusty BB’s (flyovers); Heard Junco, RB Nut and flyover Siskins. I guess winter is coming…
