New info on Cassia Crossbills in Colorado

[Nathan Pieplow]

Hi all,

Today the Finch Research Network published a guest blog that I wrote, summarizing the remarkable phenomenon of Cassia Crossbill sightings in Colorado in the past two years. I also reveal the belated discovery of a much earlier record of the species for the state, and comment on the implications for Cassia's species status.
