Hi Bill and All,

Looking at eBird there is one report of Red Crossbill, from Oak Openings in
January.

Three reports of White-winged Crossbill. Montgomery(Dayton), 2 on 2-18,
Delaware, 5 on 2-19, and Bay Village, 4 on 2-20.

Interesting how these were found in similar numbers on consecutive days
moving south to north in roughly a straight line running SW to NE.
