That's interesting though they sometimes cooperate. Only time I really see them do that here is when it's the offspring of one. Perhaps it has to do with the species of hummingbird? The ones where I am are all Ruby Throated ones.

- wiredfool 11y agoWe've got Rufous and Anna's hummingbirds. I think the cooperation comes almost as a phase transition, when the density of hummingbirds gets high enough, there's less of an advantage to chasing off a rival because there's always another bird to grab the spare feeding spot. So the most aggressive ones 'boil off' and the less aggressive ones 'solidify' around the feeder. There's still competition for the favored perches a little ways back from the feeder, but that's where the density is lower.
- yareally 11y agoMake sense. Guessing you're also lucky enough to have some all year round too, which would be nice. We never get more than a handful here, so can't say for sure if they'd act the same in that situation or not. I must not be on a large migration path, though I think some pass through from previously migrations at times. I'm guessing someone else has documented ruby throated behavior, so I'll have to Google around and find out.

- yareally 11y agoNice of you to put out a feeder for it. I would feel bad as well if I didn't and saw one here, lol.
