Summary

Data presented are results of surveys and monitoring in 2018 for Southwestern Willow Flycatcher (Empidonax traillii extimus) in San Diego County, California. Surveys were conducted at locations along Escondido Creek, Los Penasquitos Creek, San Diego River, Otay River, and the San Luis Rey River, and nest monitoring was performed at three locations along the San Luis Rey River downstream of Lake Henshaw (Cleveland National Forest, Rey River Ranch, Vista Irrigation District). Surveys were conducted along multiple sections of the river where permission to access properties could be obtained. Locations were surveyed using a standardized protocol three to four times between 15 May and 31 July. The number, age (adult or juvenile), sex, banding [...]

Purpose

The purpose of this study was to determine the size and distribution of Southwestern Willow Flycatcher populations within San Diego County, and to collect demographic data to better understand population trends and conservation needs of flycatchers. This study was part of the San Diego Management and Monitoring Program’s (SDMMP) regional monitoring and management of sensitive species and habitats on conserved lands in western San Diego County. The SDMMP coordinates science-based biological management and monitoring of lands in San Diego that have been conserved through various conservation planning and mitigation efforts. The results of this study will be used by managers to develop specific management goals and objectives to ensure the species’ continued existence in San Diego County.
