2006 VWS Bald Eagle Survey Results

Hello Everyone: I would first like to THANK all of the volunteers who spend hours each year monitoring the Bald Eagle nestsites in your area. Many of you are recipiants of this e-mail. If I missed anyone, please forward. A heartfelt thanks for your continued dedication and support.
This Survey includes confirmed bald eagle nestsites along the Calfornia Central Coast Region, excluding Lake Cachuma in Santa Barbara County. This covers an area from just North of San Francisco Bay Area, East to Interstate 5 and South to Santa Barbara County.
Locations given are intentional VAGUE in order to protect them. Many, if not all of these nestsites are from first, second, even third generation REINTRODUCTION efforts of bald eagles from either Ventana Wildllife Society, at their Big Sur fieldstation , or Institute for Wildlife Studies restoration efforts on Catalina Island, . Please checkout their websites for more information on their bald eagle restoration efforts and other exciting programs. The number of nestsite territories and eaglets that actually fledge each year is probably higher than given, for in some cases the nests have been in existance and productive longer than reported to me AND let’s face it………… this is a HUGE area to monitor . Helicopter surveys would give a more accurate accounting of what is actually taking place each season, but the overall trend of continued expansion is apparent and a credit to the two non-profits listed above , and all the collaborators of the CA. Bald Eagle Working Team. As you read below…………… a lot can be said for the obvious benefits of man-made reservoirs for the successful restoration efforts of Bald Eagles.
