Disproved “Positive” ID

A couple of birders we had never met before joined us along the sidewalk running next to the Historic Ottawa Beach area.  A small bird hopped back and forth across the sidewalk and even though it was extremely poor lighting the other two birders ID’d the bird as a Palm Warbler.  I wasn’t so sure so I took a couple of Documenting Shots.  Back home it turned out to be a Chipping Sparrow.
