I stopped by McKenny Hills Neighborhood Park in Forest Glen around
noon. There was a Mourning Warbler at a viny spot near the bridge. A
cuckoo was around the Glenmont Recreation Center parking lot, it could
well have been a Black-billed Cuckoo, but I would have preferred a
better look. A few of the more common warblers and a Veery were also
seen.
