“ The Piñon Jay, locally known as ‘Nutcracker,’ ‘Maximilian’s Jay,’ ‘Blue Crow,’ and as ‘Pinonario’ by the Mexicans, is rather a common resident in suitable localities throughout the southern portions of its range, while in the northern parts it is only a summer visitor, migrating regularly. It is most abundantly found throughout the piñon and cedar-covered foothills abounding between the western slopes of the Rocky Mountains and the eastern bases of the Sierra Nevada and Cascade ranges in California, Nevada, and Oregon. ”
