Cassia crossbill crossbill was in a coevolutionary arms race with the lodgepole pine, further leading to habitat isolation. In 2016, it was identified as phylogenetically distinct from the other call types. This is an example of sympatric speciation. In 2017, the AOU reached a consensus and split the South Hills crossbill from the red crossbill and rename it the Cassia crossbill, because its habitat resided in Cassia County, Idaho. The Cassia crossbill will exclusively forage for lodgepole pine cones that are found in the South Hills and Albion Mountains region. A primary reason why this species of crossbill can exist in such
