Light migration up the Eastern Flyway

Light winds last night triggered migration along the east coast. Here’s the radar from sunset last night through 5:00am this morning.

Conditions weren’t ideal last night, but they were “good enough” to trigger some migration over the region. What started off as light southwest winds eventually turned northwest by morning and birds could be seen moving in a general SW->NE trajectory over the region. Expect turnover at most locations today with the best opportunity for new birds at coastal locations such as Sandy Hook (but densities will not be exceptional). Otherwise expect birds to be dispersed across the landscape today. Expect a better coastal push tonight as winds start out stronger out of the southwest and again turn northwest by morning.

Good Birding
