From the author: While conducting fieldwork on the breeding ecology of grassland birds at Kennebunk, Maine, we documented the existence of extended flight-songs of Vesper Sparrows (Pooecetes gramineus). In general, we observed this behavior very infrequently, usually less than three times per breeding season. Extended flight-songs were about three times as long as primary songs and contained elements not typically found in primary songs. Extended flight-songs occurred more frequently late in the breeding season. Within the subfamily Emberizinae, extended flight-songs have now been documented for at least 10 species but their behavioral function remains unclear. Received 8 Nov. 1993, accepted 21 April 1994.
