We saw a male Lawrence’s Goldfinch from the Oursan Trail about 2 miles west of the trail junction with Hampton trail. There are several access points to this EBMUD property around Briones

A lot of the same birds continued today, which have been seen for the last week or so. I had Yellow Warbler and Western Tanager sightings, The White-breasted Nuthatch family appeared near the

This morning I saw and photographed an Ash-throated Flycatcher in the wooded area of Cesar Chavez Park. The bird flew off, seemingly to within the nearby trees, and wasn't located in the following ten
