Editing Clark's nutcracker (section)

==Distribution and habitat==
This species is present in western North America from [[British Columbia]] and western [[Alberta]] in the north to [[Baja California]] and central [[New Mexico]] in the south. There is also a small isolated population on the peak of [[Cerro Potosí]], elevation 3,700 metres (12,200&nbsp;ft), in [[Nuevo León]], northeast [[Mexico]]. It is mainly found in mountains at altitudes of 900–3,900 metres (3,000–12,900&nbsp;ft) in conifer forest. It is not migratory except in the sense of moving back and forth locally between areas of higher and lower elevation. Outside the breeding season, it may wander extensively to lower altitudes and also further east as far as [[Illinois]] (and exceptionally, [[Pennsylvania]]), particularly following any cone crop failure in its normal areas.
