24 September 2019 – Ruby-throated Hummingbird and Nashville Warbler; plus bonus birds

Birds on the move captured on Nexrad radar tell an important story on the evening of Sep. 23 to the morning of Sep. 24. First, watch migration blow up after local sunrise in the eastern US, and progress to the west.

As the night wore on, storms began to flare up in Oklahoma. Here in Stillwater those storms hit between 1:30 and 2:00 am on Sep. 24. As the storms expand, migration stalls: Birds put down to avoid the storms and for people on the ground, that’s a fallout.

Was there evidence of this fallout on the ground?

Well, there was a bonus Canada Warbler in that troublesome northeastern alcove of the Food and Agricultural Products Center. (This was in addition to a Mourning Warbler and a Wilson’s Warbler I found there on Sep. 21.)

There was a big flight of Nashville Warbler in Stillwater, too. Twelve were reported from Couch Park. I found one in the southwestern alcove and a Ruby-throated Hummingbird in the northeastern alcove.

 

10–11 March 2015 – no casualties

Pretty good flight last night in the Southeast, but those birds hit a wall in the Mid-Atlantic:

Right now we’ve got a pretty powerful system along the Texas Coast  – could be in for a fallout tomorrow afternoon – but things look clear tonight in the Plains for a big push of northbound migrants.
