Three Edmonds birders made the 3day trip to the South Hills in southern Idaho for the Cassia Crossbill. We drove about 750 miles on Monday and stayed in a motel near Twin Falls. It took about an hour to get to the first site, Diamondfield Jack Campground Parking lot. Cassia Crossbills were evident almost as soon as we arrived. We saw at least 6 birds. Only views were on treetops of Lodgepole Pine feeding on cones We were not lucky enough to find any on the ground.
The birds frequently called and, from the recordings we had listened to prior to the trip, confirmed the identification. Bills appeared on the larger side compared to Red Crossbill.
