The purpose of this study was to document the status of vireos and flycatchers along an 18 kilometer stretch of the San Luis Rey River from College Boulevard in Oceanside, California, east to Interstate 15. These data, when compared with data from other sites, will inform natural resource managers about the status of these endangered species on the San Luis Rey River and guide modification of land-use and management practices as appropriate to ensure the species' continued existence.
