The latest flight


Winds turned ESE yesterday, as the latest low-pressure system and cold front approached from the west. This resulted in light to moderate migration across the Eastern and Mississippi flyways last night, with the heaviest migration occurring well to our south along the Gulf Coast and Florida Peninsula. Migration over New Jersey, however, was quite low an restricted to the western half of the state. Here’s the radar from 7:00pm last night through 5:00am this morning.

Easterly winds clearly favored inland locations last night, as no birds appeared to be moving into or out-of the eastern half of New Jersey during the last twelve hours. Based on this, I wouldn’t expect much in terms of noticeable change, except maybe at spring migrant traps along the Delaware river and into the northwestern portion of the state.

With southeast winds forecast again  tonight, we could see a second push of birds into the region by tomorrow morning. Most of this depends  on the intensity of the precipitation associated with the passing cold front. Either way, easterly winds should  favor inland migrant traps on Monday morning.

Good Birding

  1. Lots of Blue Jays seen in Mahwah, NJ (zipcode 07430) area this morning (28th March). It was noticeable that these guys came just this morning. Yesterday, there was a no show. Will keep an eye tomorrow AM and report. (precipitation tomorrow may turn them off)
