In On the Move, our regular column about migration, we present pairs of distribution maps from eBird that you can use to compare where interesting birds are at different times of year. We featured Sedge Wren, pictured above, in our June 2018 issue.
Sedge Wren, the only North American wren with a combination of barring on the head, wings, and tail, is known for being widely nomadic, secretive, and difficult to study. During the breeding season, it is perhaps best located by its song, a dry staccato chattering that rises from the sedge meadows, bogs, and prairies that it inhabits. In June, Sedge Wren occurs across the Midwest and portions of the Great Plains, but breeding occurs in different parts of the breeding range at different times. The birds first nest primarily in the Midwest and southern Canada, and in late summer, they make a second attempt either south or northeast of their first spots. By January, most Sedge Wrens that breed in the United States and Canada have flown to the southeastern states and northeastern Mexico. Male Sedge Wrens are prolific singers and are unique for improvising species-typical songs rather than by imitating the songs of other Sedge Wrens.
