Irene Wright noticed a couple of hummingbirds out here window recently in Toledo. And when they kept squabbling, Ilene tracked down her camera and caught a slice of the action between them. As pointed out in an earlier story about Rufous Hummingbirds they raise having a bad attitude to a high art. In this case, the female at the window-side feeding dish is interrupted by an aggressive male hummingbird who obviously wants to have the whole feeding tray to himself. Thankfully that NEVER happens in the daily comings and goings of our human existence.
The lesson learned here may be to have two separate but equal feeding trays so that those who are in to it for utilitarian reasons, like hunger or love of the color red, will have reasonable access to it. Others will have to resort to seeing themselves as simply greedy.
