Weekend of May 24-26: migration

For the last several days the winds have been mostly from the north, not really good conditions for migration, but some migrants have been moving anyway. The numbers and diversity have continued to be good in many habitats in northwestern Ohio. (This is gleaned from reports from others, since I was away in Boston for part of the week.)

Mark Shieldcastle, who has many years of experience in studying the migration here, tells me that he expects the third major wave to hit sometime late this weekend. Based on current weather predictions, I would have to agree. The forecast still calls for northeast or north winds through Saturday and Saturday night, the 24th, with winds finally shifting around to the southeast on Sunday morning and then to the south. We could see a good movement of daytime migrants on Sunday, and I expect a really good arrival of birds during Sunday night, so that Monday morning, May 26, could be excellent. (There’s likely to be some rain, but that could make it better – it appears it will be mostly clear to the south of us, so a lot of migrants could be moving north, running into weather near the lakeshore and stopping here.) May 26th is not too late in the season for an excellent variety of migrants to be around, with lots of flycatchers, thrushes, and Red-eyed Vireos expected, and a warbler flight characterized by Canada, Wilson’s, Blackpoll, Mourning, and Connecticut Warblers and lots of American Redstarts.
