This white-winged crossbill was found at the home of Pat Theis on Melmore Street and identified by local bird expert Tom Bartlett. Along with an invasion of snowy owls this winter, Bartlett said other northern species to visit in large numbers have been this species and common redpolls. Both are fairly uncommon in Ohio. He said he has seen white-winged crossbills only six times in the last 40 years. He said the birds have a unique bill structure. The top and bottom of the bill crosses over, which allows them to bite at a cone and pop out the seeds.
