[Tweeters] Peaceful coexistence among Annas

[Cooper PhD, Jonathan A via Tweeters]

Hi Tweeters - Our hummingbird feeder is normally the scene of hot disputes, with a competitive male wasting no time to chase off other visitors. The other evening, in the half light, we were surprised to see not one but three, then four, Annas perched around the rim, one at each of the drinking holes. They took it in turns for one to drink while the other three watched, bills up. This went on for several minutes until it got too dark for us to see. Why such peaceful co-existence?
