Reverse Migration?

Saturday’s snowstorm brought some unusual news from the northeast portions of Minnesota. Check out this report from the MOU (Minnesota Ornithologists Union) listserver:

I also saw a lot of “reverse migration” yesterday around Two Harbors.
There was a constant stream of Yellow-rumped Warblers, Tree
Swallows, Ruby-crowned Kinglets and Hermit Thrushes flying southwest
along the lakeshore and out over the lake.  I saw at least 80
yellowlegs (mostly Greaters) in several flocks, all flying southwest
along the shoreline.  Smaller numbers of raptors and waterfowl were
also moving southwest throughout the day.  In my yard, I had a flock
of about 250 Rusty Blackbirds.

Spent at least five hours at Stony Point (North Shore), and Lester
River (Duluth), shore fishing. Was amazed by the amount of yellow
rumped warblers I saw migrating SOUTH! That’s right, well over 200
yellow rumped warblers, over 100 tree swallows, several loons, 10+
tundra swans, sparrows, and a few hermit thrushes, all of them moving
down the north shore towards  Duluth. 

It looked and felt like fall migration. That 200 number for the
yellow rumpeds is a very conservative est. in my opinion. 

Happy  Birding, and hopefully warmer,

It was a weird day in Crane Lake too. During the storm there were birds everywhere. Maybe the birds here were migrating south from Canada and the International Falls area where they received upwards of 9 inches of snow. We only received about 3 inches of snow in the Crane Lake area. Sunday, after the storm, things were pretty quiet birdwise. There were still several species of birds on the tar road where the snow had melted – most notably Killdeers trying to stay out of the snow.

It will be warming this week and all this snow will be history soon – can’t wait!
