Category: NEXRAD Migration Study

  • A plea for feedback

    We’ve got a great community here. According to my site stats upwards of 600 unique visitors come here for their daily dose of radar and migration; that’s fantastic! Unfortunately my part is only half of the equation, and without your feedback the site remains a one-way street with little usefulness in terms of ground-truthing (and hence, little use as an archive of migration over the Upper Midwest). So I’m asking you today to please consider providing some comments following a day of birding so we can all learn more about the relationship between what we see on the radar and what we find on the ground! A comment can be as simple as a one-liner, a copy-pasted post you might make to your local listserve, or even copy-pasting your eBird list. It shouldn’t be daunting- anything is better than an empty comment section! 🙂

  • BOOM! It’s MAY!!!

    BOOM! It’s MAY!!!

    Migration was hot and heavy along the Central and Mississippi Flyways last night, while high pressure over the Mid Atlantic and Northeast kept birds down for that part of the world. A stalled front stretching from the Great Plains to the Upper Midwest marked the boundary (and fallout line) for the Central US, and migration continued across the Gulf Coast, Desert Southwest and up the Pacific Coast as well.

  • Heavy migration finally reaches the Upper Midwest

    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.

  • More broad front migration across the US

    More broad front migration across the US

    Continuing on yesterday’s theme, migration was widespread throughout the US as several fronts pushed eastward across the Midwest and Eastern Seaboard. Many birds were seen coming across the Gulf of Mexico and from the Caribbean, and migration was evident along both coasts throughout the morning hours. Migration was still heaviest in the southern part of the country which bodes well with the seasonal phenology of available resources… also suggesting that the Upper Midwest will have to wait a little longer for a big influx of Neotropical Migrants!

  • Heavy migration across the US

    Heavy migration across the US

    Migration was hot last night from sea to shining sea, the only exception being right under the strong low pressure system across the Missouri/Kentucky area. The radar showed strong trans-gulf migration yesterday afternoon followed by heavy nocturnal migration from the Caribbean to New England, and west to the Pacific Ocean. Good stuff! Spring has SPRUNG!!!
