Migration over Jerze

The Garden State experienced a good influx of birds, as winds turned southwesterly late last night.
Here’s the radar from sunset last night through 5:30am this morning.

Frames are every 1/2 hour for reflectivity and velocity, and every hour for the regional composite. Click on the thumbnail to view the full-sized animation.

Similar to yesterday, migration was heaviest over the interior Mid-Atlantic states, while light to moderate pulses were detected entering New Jersey from the southwest and central parts of the state. The composite image does a good job of putting it all into perspective. Check out the strong signals over Virginia, Maryland, and Pennsylvania, compared to those over New Jersey.
Still, there was a good push of migrants into the state, with an additional pulse of birds by late morning into the southern half (something we didn’t see last night). New birds should be present at most locations today, with the densest aggregations in the interior (such as at Garret Mountain). I’m heading for Sandy Hook based on the west winds, but migration there did appear to be light.

Hopefully the westerlies will blow some raptors, Rough-wing Swallows, or an early bunting out to The Hook!

Good Birding

  1. 38 species at CF this morning. Nothing new for the year–and surprisingly no warblers. Highlighs incl. my first SEEN VA Rail of the year, 2 PB Grebes, 1 Snipe, 5 Phoebe, a heard only singing RC Kinglet, and my latest ever Tree Sparrow. No Ibis seen today.
    Yesterday’s southerly flow produced an adult Bald Eagle and a First of year Greater Yellowlegs in the evening.

  2. Sandy Hook
    Time: 8:45am – 12:45pm
    Locations: K Lot / Battery → Locust Grove → The Bowl → Raccoon Alley/ Road to Nowhere → Horseshoe Cove
    Participants: Rutgers University Ornithology class
    Notes: Winds last night started at E, changed to S and SW during peak migration, and ended at W at daybreak. The radar indicated that birds were clearly moving over Sandy Hook at 5:30am, and upon arrival at 8:45 the fog was very thick, leading to many birds overshooting the coast and making landfall in the early morning. We saw flocks of dozens to over one hundred blackbirds (Red-winged mixed with Common Grackles) and warblers (almost all Yellow-rumped) coming in off the ocean between 8:45 and 10:45am.
    Bird diversity consisted mostly of typical early April species; with very large numbers (100+) of YELLOW-RUMPED WARBLERS (many of which were both singing and coming into specky breeding plumage) GOLDEN-CROWNED KINGLETS, and SONG SPARROWS, dozens of EASTERN PHOEBES, about a dozen NORTHERN FLICKERS, our FOS E. PALM WARBLERS (4), RUBY CROWNED KINGLET (1), BARN SWALLOW (1), N. ROUGH-WINGED SWALLOW (1), SAVANNAH SPARROW (1), and GREAT EGRET (1).
