I've seen as many as three Anna's at the same time.
Being Anna's, that was one at the feeder, while the second bird chased the third away, because that's how Anna's roll!
A female has taken up residence in the backyard.
There's also a male active in the backyard.
See his tongue?
At this point, the backyard is a battle ground, though I think the female is winning.
While the male comes to drink, she's the one hanging out and defending her territory.
I wonder if she is beginning to scope out a nesting site.
If so, it's good that the male is hanging around.
