Update: migration forecast 4/29 to 5/1

As of late evening on Wednesday April 28 (4/28): temperatures are going to be chilly again tonight in n.w. Ohio, but the sky is clear and the wind has shifted to southerly already, earlier than had been predicted. I expect there will be a decent arrival of migrants on each of the next three days -- Thursday through Saturday, 4/29 through 5/1. Right now I'm guessing that Friday the 30th will be the biggest day for new migrants to show up, but Saturday may have somewhat more species even if there are fewer individuals. Friday it's supposed to be very warm and windy in the afternoon; Saturday there are likely to be scattered showers but that shouldn't spoil the birding.

As long as the wind is strong out of the south, the biggest concentrations of migrants are likely to be near the immediate lake shore, such as the shoreline woodlots at Metzger Marsh, Magee Marsh, and East Harbor State Park. But the woods at Ottawa Nat'l Wildlife Refuge should also hold a lot of migrants every day from now through the end of May. The boardwalk and trails behind the Ottawa NWR visitors' center are almost always productive in spring, even when the wind shifts and the shoreline spots slow down a lot.
