It wasn't until last week that I remembered I even had the tracks on my recorder. I downloaded the files and started to analyze them hoping for good tracks of Type 5 "Lodgepole Pine" Red Crossbills. Things just didn't look right when I saw the calls on the spectrogram. The calls resembled a horizontally flipped lower case "h". These calls matched Cassia Crossbill when compared to examples on eBird, within resources like https://ebird.org/news/crossbills-of-north-america-species-and-red-crossbill-call-types/ , and in Nathan Pieplow's "Peterson Field Guide to Bird Sounds of Western North America".
The exact location is in my eBird checklist. Folks may still want to go look in case the birds have stuck around. They are normally more sedentary than other crossbills. But, no guaranteess that Grand Co. Rd 555 is open at this time of year. Google Maps shows it as closed, but who knows. It's a good dirt road and would be drivable with any vehicle as long as there isnt' any snow or mud.
