The South Hills crossbill (proposed scientific name Loxia sinesciuris) is a passerine bird in the family Fringillidae. It's endemic to the South Hills and Albion Mountains in southern Idaho.[1] South Hills crossbill rarely interbreeds with other call types that move into the South Hills of Idaho yearly,[2] and can be considered to represent a distinct species [1] via ecological speciation.

It has been proposed as a separate species, but the American Ornithologists' Union failed to find consensus on the issue[3] and thus the South Hills Crossbill is still considered a subtype of the Red Crossbill.
