[EBB Sightings] Costa's Hummingbird

This afternoon about 3:30 I had a Costa's Hummingbird show up at my backyard
feeder. Required several more hours of waiting to finally get good digiscope
pics. Very nice male with full gorget. When sitting at the feeder the folded
wings reach right to the tip of the tail. New yard bird!
Earlier today at Lake del Valle I had several Yellow Warblers at the south
end of the lake.  Stuck out again on Black Terns at the Hayward Marsh but
found one Wandering Tattler at the San Leandro Marina along with several
Least Terns.
Good birding.
