Heavy migration finally reaches the Upper Midwest

With a few exceptions, migration was hot and heavy or most of the US last night. Birds continued to stream across the Gulf of Mexico and Florida Straits and make landfall throughout the US Gulf Coast. Birds also poured up through all four major flyways- the Pacific, Central, Mississippi and Eastern. High pressure over the Northeastern US as well as in the Four Corners region of the west, represented the only areas where migration was not evident on the radar last night. Continue reading

Spring has SPRUNG!!! Continue reading

The floodgates begin to open over the Central Flyway

It might be easier to discuss where migration didn’t occur last night rather than where it did, given how widespread it was over the country. High pressure over New England, the Ohio Valley and the Great Basin kept birds down last night, while a series of low pressure systems and associated fronts triggered migration along both coasts and especially up the Central Flyway into the Upper Midwest.
