The white-necked raven (Corvus cryptoleucus), a close relative of the common crow, is indigenous to southwestern United States. Because in parts of its range it has gained the same ill repute as acquired by the crow and magpie in their respective ranges, a 5-year detailed study of its activities and food habits was made, during which many field data were gathered, and the contents of 827 stomachs were analyzed.
