I spent a few hours hiking and biking around this sprawling park in south Columbus.  It contains several riparian corridors and a few large floodplain forest patches, so can be a good migrant trap.  It worked quite well this morning, though I had to dodge the runners in a large charity race along the trails.  I visited the Confluence area, the Borrow Pits along the trail (near I-270) and the Groveport Blacklick Bikepath (GBBP).  Thrushes were the big highlight, while warblers were once again in short supply.  Notables included:

Herons- the borrow pits along I-270 are still strangely low in waders; I could only find 2 Great Blues and 2 Great Egrets there today.

Flycatchers - not much other than a few E.Wood Pewees.

Swallows - only Rough-wings (about 12), mostly near Blacklick Creek

Vireos - singing Yellow-throated and Warbling near the Borrow Pits in a riparian forest along Alum Creek.

Red-br.Nuthatch - another of these little vagrants was lurkind in the pine grove at the Confluence area.

Thrushes - good #s of Swainson's (20+), but also had 4 Gray-cheeked, 1 Veery, and 2 Wood Thrushes.  Also had over-flying groups of E.Bluebirds at several areas.

Mimids - many Catbirds, especially along wood edges.  Also had 2 Brown Thrashers along the powerline right-of-way along the eastern edge of the Confluence area.  Strangely, no Mockingbirds around the Confluence entrance (usually a good location for them).

Warblers - not easy to find; the list included Tennessee (5), Parula (1 singing male), Black-thr.Green (2), Magnolia (3), Cape May (2), Redstart (5), plus about 12+ unidentified birds.

Blackbirds - several large flocks of Redwings, but no grackles.  A young Cowbird was along the GBBP.

Other migrants - Rose-br.grosbeaks and Indigo Buntings at several locations, but no Tanagers or Orioles noted.
