[EBB Sightings] Allen's Hummingbirds, Warbling Vireo

Yesterday our backyard birding was quite interesting.  Early in the  
morning a juvenile Cooper's Hawk flew into the yard and perched in  
our neighbor's redwood tree, only to be harassed by several Anna's  
Hummingbirds which apparently caused it to make a quick departure.   
The Warbling Vireo returned to our bird bath frequently and drank  
from the dripper.  We had really good looks, even a scope view.  In  
addition, a female Selasphorus hummingbird was a frequent visitor to  
the feeders, and today she was joined by a male Allen's Hummingbird  
so we are assuming that she is a female Allen's.  With temperatures  
at 100+ degrees here, we have concentrated on our backyard which has  
provided some good visitors.

Good birding,
Paul and Nancy Schorr, Antioch
