[cobirds] Great Red Crossbill resource

Wanted to pass along this link to a great document on Red Crossbill from the Finch Research Network:

A Crossbill's Guide to Conifers of Western North America: A How-To for Finding Crossbills

I had Red Crossbills (Type 2) at Genesee Park, JeffCo, yesterday, where there is a prodigious developing Ponderosa cone crop.  The cones are still maturing and are tightly closed and green, but the crossbills can still get at the immature seeds, I've seen.  One male was singing.
