Bighorn sheep near Salida
Though bighorn sheep are not birds, I think many birders enjoy seeing them. Highway 50 from Canon City to Salida is named Bighorn Sheep Canyon due to the several herds that have historically occupied this area. In my experience they are best seen from late fall to early spring, times when the number of humans and human activity is significantly reduced.
Today I was fortunate to this large herd of 14 bighorn sheep between Howard and Salida, a few hundred feet across the Arkansas River. On my way back from Salida I saw 2 more bighorn sheep close to Texas Creek.
