The Chestnut-collared Longspur is a rare winter visitor and migrant in Arizona, primarily recorded in the southeastern portion of the state. This grassland species breeds on the northern Great Plains, but small numbers occasionally disperse south into Arizona during migration or winter. Sightings are typically in open, short-grass habitats such as agricultural fields or native prairies, where flocks may mix with other sparrows and longspurs. Distinguished by the male’s striking chestnut nape, black breast, and white underparts in breeding plumage, the species is far more subdued in winter, blending well into the dry grass landscapes of Arizona. Records remain irregular, making the Chestnut-collared Longspur a sought-after bird for state observers.
