Guide to Boreal Birds
A bird of the wetlands during the breeding season, the Swamp Sparrow appears in a variety of other habitats during migration and in winter. It is rather shy, but responds readily to any squeaking noise, and can usually be lured into view by a patient observer. It is never seen in large flocks like the White-throated and White-crowned sparrows, but is usually found singly, foraging on the ground in rather dense cover.
