This morning I hit several urban parks along the Scioto River in near-west Columbus suburbs, including Grandview Heights, Sullivant Trace, Marble Cliff, and Griggs Dam.  Nothing extraordinary, but a surprisingly diverse set of birds for so urban a set of locations.  The list included:

Cormorants - flyovers at several places, probably commuting from the Campbell Mound Quarry colony.
Cooper's Hawks - one bird was calling at Sullivant Trace, and others were flyovers at Grandview's Wyman Woods and Griggs Dam
Ruby-thr.Hummingbirds - every site had 1-2; they're more common here than in more distant rural parks
Acadian Flycatchers - birds below Griggs dam & at Sullivant Trace were expected; one in a forested Grandview yard was not
Great Crested Flycatchers - singles were at every spot, which was gratifying for these big flycatchers
Cliff Swallows - the Fishinger Bridge colony appears strong, with 25-30 nests
Rough-winged Swallows - 25-30 were swirling around the river and disc golf course below Griggs dam
Bank Swallows - 15+ were along this same stretch of river, implying a colony somewhere in the quarry to the west of there.
Warbling Vireos - quite widespread, with birds at Sullivant Trace, Marble Cliff (4), and below Griggs dam (4)
Yellow-throated Warblers - also widespread, with much the same distribution as Warbling Vireos, though only 1 per site.
Prothonotary Warbler - 1 bird was still singing on territory along the river below Griggs dam.
Baltimore Orioles - every site had a few; the riparian strip below Griggs dam had 6-7.
Orchard oriole - 1 was singing around the edge of the old flood-control impoundment marsh along Sullivant Trace.
