Subject: [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
<https://finchnetwork.org/a-crossbills-guide-to-conifers-in-western-north-america?fbclid=IwY2xjawLXRtFleHRuA2FlbQIxMQBicmlkETFFUmE2b2V0aXlDZUttakFwAR6EK5wz_j4RIasPgE-yL3VoxqWtxtINoD-xe13jU33Af8p8HF3ImunAEsJ6Zg_aem_vNyb9a3UKiPtl3uW6rweEw>

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.
