May 9-10: Major migration wave continues

Friday, May 8, was a major day at Magee Marsh, Ottawa NWR, and nearby areas on the lake shore of n.w. Ohio, as already reported. Saturday was another huge day; numbers were somewhat reduced from Friday (partly because a lot of White-throated Sparrows departed) but variety was still great, with many more Blackpoll Warblers and others apparently having arrived overnight. During the day Saturday the wind shifted to the west and the temperature dropped. The north edge of the woods (south edge of the parking lot) at Magee was outstanding all afternoon, with many, many warblers feeding very low, apparently resorting to that area to be out of the wind.

Early indications today (Sunday May 10) are that numbers and variety are still excellent: the northwest winds overnight apparently kept yesterday's hordes of warblers and other migrants from departing. With the cooler temperatures today, the birds are still feeding low, for excellent views.

Numbers will probably continue to be fairly good through Monday, then drop off Tuesday and Wednesday. Right now it appears that Thursday, May 14, may be the next big day, but I haven't taken a detailed look at the weather yet and I may have to revise that prediction.
