They've been absent from my OBBA2 blocks for 1-2 weeks now.  They've usually been one of the first birds to leave their nesting areas in central Ohio, and I can count on finding small groups of them in migrant traps along water (such as Alum Lake and Darby Creek) by now.   As a good comparison, I'm visiting relatives in western Massachusetts right now and spent the morning in ideal Baltimore Oriole habitat along the Connecticut River.  Plenty of E.Kingbirds, Yellow Warblers, Warbling VIreos, and large flocks of swallows,.....but no Baltimore Orioles.   They're already largely gone from here.
