About the Lark Sparrow

The lark sparrow (Chondestes grammacus) is a fairly large New World sparrow. It is the only member of the genus Chondestes. It breeds in southern Canada, much of the United States, and northern Mexico. It is much less common in the east, where its range is contracting. The populations in Mexico and adjacent states of the United States are resident, but other birds are migratory, wintering in the southern United States, Mexico and south to Guatemala.

It is a very rare vagrant to western Europe, with two accepted records in Great Britain in 1981 and 1991. The lark sparrow is distinctive. Adults have a typically sparrow-like dark-streaked brown back, and white underparts except for a dark central spot. The cheeks and crown sides are chestnut, with white eyebrow and crown stripes. The dark tail's corners are also white. Young lark sparrows are duller, and the underparts are streaked.
