Remeber that different types (subspecies? species? It's an active research question) of Red crossbills have different calls.

These links may help:

There is also a local (PLU?) biologist, Julie Smith, who works on vocalizations of Red crossbills. If you can ID the calls she may be interested (though she really needs recordings).
