No migration as warm front pushes northeast


Winds were southwesterly as the thunderstorms rolled in on a warm front last night. Here’s the radar, mostly so you can see what “no migration” looks like, and how precipitation has a very different signature than birds. The frames are from 7:00pm last night through 5:00am this morning. For whatever reason the Fort Dix radar was down, so only the Dover radar and the regional composite are shown.

Frames are every 1/2 hour. Click on the thumbnail to view the full-sized animation.

Not much going on bird-wise last night, as winds were unfavorable for most of the night, and large thunderstorms moved over the region. Expect this to change over the next 18 hours, as winds shift to the northwest during the day, and go slack tonight. Unfortunately the prospect of fallout conditions tomorrow is looking low, since the wind forecast is calling for a faster shift to unfavorable winds overnight tonight, and precipitation has been almost entirely taken out of the equation.

Hawkwatches may have a good flight early today while winds are northwesterly, so if you’ve got the time you may want to hit up one of the nearby ridges.

Good Birding

One response to “No migration as warm front pushes northeast”

  1. I’m not sure if it was a result of a pre-dawn shift to NW winds or just local movement, but Duke Farms had some new birds today.

    a modest flight of neotrops consisted primarily of magnolia warblers with approx. 20 throughout…a pair of empidonx spp., yellow throated vireo, ovenbird, and black and white warbler were also noted.

    short distance migrants continue in strong numbers…many migrant catbirds, towhees, and 12 brown thrashers were counted.

    10 Eastern Phoebes seemed unusually high for mid-september to me. Also on the late species front, a single Chimney Swift was present.

    for diurnal birds- 8 Kestrels, 1 osprey, 1 sharp-shinned hawk

    Wed-Fri this week are looking good. Maybe the “broadwing window” for this fall.
