Williams North Kern Water Storage District P.O. Box 1195 Bakersfield, CA 93302 Dear Chuck, Here's the final report of the'1994 Willow Flycatcher/Brown- headed Cowbird study. Thank youand the Kern River Water Interests for supporting this study. Your support allowed us to expand the study. As a result, Willow Flycatcher productivity increased along with our knowledge of Willow Flycatcher ecology. This information is invaluable in developing a successful management plan for the species We see our research and management program on the Willow Flycatcher continuing for the next four to five years.' We .are developing a management model, both from data collected on thi~':~ project and elsewhere in California, whichwill' determine' '.the:~'":":'~': intensity and frequency of trapping needed toprovide population of Willow Flycatcher in the South,Fork Valley. hope that the Kern River Water Interests will continue to support this research and management'program. We feel that together we can develop a long-term management plan for this population of Willow Flycatchers and other riparian species that. will be' beneficial to both wildlifeand the Kern.River Water Interests...-.
