Park, Alameda Co, Calif: 4 σσ Feb.24 301 Camino Pablo, Orinda, Contra Costa Co, Calif: 1 σ - first in yard this spring for me, although Bill Principe had seen one here ~ 1 week earlier. Mar.13 301 Camino Pablo: 1σ has claimed the front porch feeders and drives away all the Annals. As I have observed many times before, a σ Selasphorus is almost always victorious in combat with Annals and they can successfully defend against several Annals.
