Popis:	Some birds exhibit clustered breeding in which all-purpose territories are densely packed, leaving intervening but apparently suitable habitat unoccupied. Clustering could be ecologically driven by material resource patterns or socially driven by social or sexual benefits. Least Flycatchers (Empidonax minimus) breed in clusters in forests over much of North America. In 2003, we mapped all Least Flycatcher clusters along 18.7 km of secondary roads in central Ontario. In May 2004, we broadcast recorded territorial song in five areas not used by Least Flycatchers in 2003, but in the same study area. During settlement, we found Least Flycatchers in the established clusters, in three of five treatment sites, and in one nontreatment site. However, no pairs were noted at the treatment sites, and no males ultimately remained. One male did, however, defend a territory at a treatment site for 6 d. Despite limited success at attracting Least Flycatchers to new locations, manipulating settlement using social cues could be a useful management tool for some species.
