  • Light Migration Over NJ

    Last night saw a noticeable but less eventful movement of birds than the past few nights. This is consistent with what we usually see during migration; where during consecutive days of movement numbers peak in the first couple of nights, and then taper off as the number of birds fit to migrate decreases over time. […]

  • Birds keep movin’ along…

    Another night of migration under light NE winds. The loops are from sunset last night through 6:30am this morning. Birds are seen lifting off after sunset and continuing in a NE –> SW direction into the early morning. With no weather present to concentrate birds, the best locations will likely be those tried and true […]

  • Third night in a row!

    Last night marks the third successive night of heavy migration. Yippee! Here are the radar loops from sunset last night through sunrise this morning. It looks like the wind switched around to the NE over the course of last night, and the trajectory of birds migrating appears to follow along. I suspect Higbees will not […]

  • Today’s birds and tomorrow’s forecast

    First off, birds are on the move again tonight. I’ll post the radar by 7am tomorrow morning. Today on the ‘back 40’ the migration was evident. Conspicuously absent were tanagers and orioles…weird. From 7:30 – 9:30am Magnolia Warbler (5, all adult females) Common Yellowthroat (many) Prairie Warbler (1 adult female) Ovenbird (1) Blue-winged Warbler (1 […]

As is to be expected, last night’s migration was a little lighter than the night before (although still intense!), which I believe is due primarily to the ‘source’ of ‘ready’ migrants to our north having been depleted (a good number […]
