FYI, Anna's hummingbirds are incredibly mean as well and will viciously fight over the nectar in my feeders even when there's plenty to go around. I have many birds in my backyard but hummingbirds are by far the most selfish and aggressive.
EEmmm if your all about animal beauty
how can a Bird be mean...?
Humans can be mean
Chimps have proven to be mean
Never seen a bird be mean...only do what its survival depends on
