We have fed Anna's hummingbirds year round for 35 years, from the north sound to the south sound. This fall, their behavior is extraordinarily different.
Anna's are so territorial, it's only been an occasional thing to see more than one sit on a feeder at a time. However, this year, we've had to hang up two additional feeders (three within a few feet of each other) because of all of the activity. We've not only had four on the feeder at one time, we've had several occasions where two sat on the same flower and shared and once had six on a feeder with four flowers.
We first thought they must be all juveniles. However, we have females, juveniles and adult males all feeding together on the feeders. At times, we've had three full feeders and more birds in the air. We've never seen anything like this outside of Arizona.
We're going through a gallon of (homemade) hummingbird nectar a week, an unprecedented amount!
I wish I knew what I was doing right so I could keep on doing it!
Is anyone else seeing this unusual (for Anna's) behavior? Barbara
