[EBB Sightings] Red necked Grebe

Was still present today at the NW end of the lake at Shadow Cliffs Regional 
Park, Pleasanton ($6 entance everyday). I also saw a California THRASHER in 
the brush near the north parking lot. .  A pair of Great Blue HERONS were 
setting up housekeeping, busily rearranging the twigs in their nest at the 
southernmost pond. There were also many Tree SWALLOWS flying about. 
Regarding the grebe,  I don't think anybody's mentioned it, but our opinion 
is that it's an immature.
