And the floodgates remain open


Here’s the radar from sunset last night through 5:00am this morning.

Light northerlies last night triggered another migration event across the entire eastern flyway. This time, though, densities were lower up north, suggesting a diminishing pool of migration-ready birds. Densities down south were considerably higher also demonstrating that the mass of long-distance migrants is making its way into warmer climes. As winds turned light and NE this morning the general trajectory of migration could also be seen mimicking the shift, with many birds heading SSW across NJ. Expect inland migrant traps to be best today, especially up north where winds have already turned NE. Down south winds are still out of the WNW which will benefit Cape May, delivering a fair amount of both songbirds and raptors throughout the day. If you’re lucky you might just re-find the American White Pelican seen late yesterday evening from the Hawkwatch!

Good Birding
