High pressure over the southeastern US allowed for some migration into the Mid-Atlantic and parts of the Northeast last night. Here’s the radar from sunset last night through 5:00am this morning.

While some migration did occur across NJ, the lingering effects of the previous southeast winds are also apparent in the lack of migration along the coast. In a nutshell, birds just aren’t at the coast right now, so the bulk of the birds heading north are coming from points further west. That pattern means that most of the migrants over NJ last night were heading straight up the Delaware River, with lower densities trailing off into western and parts of central NJ. Expect the best birding conditions to be found at migrant traps along the Delaware river, such as the National Park dredge spoils and Palmyra.

As low pressure drifts north and east over the next two nights we should see more birds pushing into the region. Stay tuned as it unfolds!

Good Birding
