Subject: [obol] Re: Red Crossbill Types
If there’s someone out there who can ID each of the 20+ call types by ear
and have that confirmed by recordings, I’d love to meet them! It’s not
humanly possible. You can have a hunch based on range and general sound,
but there’s no way to be confident or accurate without recorded proof.

Anyway, my point is that while certain Types of Red Crossbill have been
confirmed to prefer certain areas of the state, birders should not
automatically eBird their sightings as those specific Types without
recorded proof. That’s a very bad road to go down as a birding community,
and first-class stringing.
