Heavy trans-Gulf arrival was followed by a major flight of nocturnal migrants across much of the U.S. last night. This included the entire southern tier of the country, the second big push into the Mid Atlantic and Northeast, a huge push up the Central and Mississippi Flyways and additional birds up along the Pacific coast.

Hot and heavy migration continued up the Central Flyway last night with the heaviest movement from Texas to Iowa. High pressure over the Great Lakes kept things a bit quieter from Michigan to the Ohio Valley, and the Northeast will have to wait for the latest low to clear before birds make it up that way in earnest. The real hotspots, last night, though, were in the metro D.C. area where heavy migration coupled with a strong low pressure system should lead to some fallout conditions this morning. Also, birders in eastern Kansas, where storms intersected birds in the early morning hours, should also be on the lookout for fallout at first light. Migration continued up the west coast as well, from California to Washington State.

Pre-sunset South Texas received some trans-Gulf migrants late yesterday afternoon, while sunset triggered migration across the southeastern US and New England. The Mid Atlantic and PA suffered another night of high-pressure-induced-migrant-shutout-fatgue, causing Drew to jump ship for Ohio and Vince to simply shake his fist at the sky over Cape May and say, “why, now that I have all the time in the world, am I being robbed of spring migration!?”. Dawn, on the other hand, finally picked up some birds in North Cackalacky as low pressure moved north and east over the Barbecue States. The Central Flyway was where all the big action was, as it lit up like Christmas after sunset (if Christmas colors were blues and greens). Migration in the west was heaviest along the Pacific coast but was evident throughout the mountainous west along with scattered precipitation.
