[EBB Sightings] Lake Del Valle

Signs of land bird migration getting started. This morning I found 3
Black-throated Gray Warblers and one Orange-crowned Warbler at the south end
of the lake under the bridge. Aside from the 30 Killdeer no shorebirds where
at the sewage ponds. 
Yesterday I had Rufous Hummingbird in the backyard for a few minutes.
