Lincoln’s Sparrow

Although this relative of Song and Swamp Sparrows breeds in New Hampshire, it is far more likely to be encountered during migration. In the fall especially, look for it in brushy areas and the edges of fields with other sparrows. If seen well, this is subtly striking sparrow, with a gray and brown striped head and fine streaking on a buffy breast. Beware juvenile Song and Swamp Sparrows, which can look quite similar. If you think you see this species south of Coos County during the breeding season take a careful second look, since it’s extremely likely to be one of its more widespread relatives instead.

Even in the North Country where it breeds, the Lincoln’s Sparrow is encountered irregularly. It is most consistently found north of Errol, with a smaller concentration in the Pondicherry area and scattered records in parts of the White Mountains. Look for it in bogs, wet thickets, and regenerating timber cuts. Often the first sign of this secretive species is its distinctive song, a bubbling series of chirps and trills similar to that of a House Wren. House Wrens don’t occur in these habitats, so if you hear one try to find the Lincoln’s Sparrow!

Historical records suggest that Lincoln’s Sparrow was scarce in the early 1900s, and not reliable in summer until the 1950s. It increased for another 20-30 years, as shown in the trend graph, but has been declining regionally since 1980. Since the species is not well-studied, we know little about what threats it might face, but its historic ups and downs might be related to shifting availability of early-successional habitat. Because it is one of our more northerly breeding species it may also be more vulnerable to climate change.
