Hummingbirds Again

My sweet kitty and I love to look outside; it is one of our favorite pastimes right now. I'm not a T.V. watcher, for one thing there isn't anything I care to watch and another thing is I get too bored just sitting there. You would think it would bore me to just sit and look out the window but it doesn't. It is fascinating to sit and see the birds, butterflies and bees. If I weren't watching I would be missing so many interesting things.For example, yesterday I posted about the territorial hummingbirds, and boy were they ever territorial today! What a show they put on for us. I put some fresh nectar in the feeder and four hummingbirds, (the most I've seen at one time), came immediately and began to fight over it. It was amazing to watch their acrobats and see them flying so many different ways. Two of them almost came right into the open window where I was sitting, (the window is only opened about six to eight inches). This isn't a good picture, because they are so fast, especially when they are fighting, but if you look on the ground you can see the orange on the male. He was the one guarding the feeder yesterday and he was losing the battle today. I believe the other hummingbird, which you can see flying up from the ground, might be a juvenile male, because he has a small red dot on his throat. I thought they were going to kill each other. Most of this fight took place right in front of the window. Would they fight like this over flowers? Is it the feeders that make them so mean or is it just their nature? It's no wonder they are so fast, they are constantly looking over their shoulders for an attack and they have to be fast to outrun the other hummers. I was thinking today that they need hummingbird Ritalin or something to calm down a bit. Boy, are they ever mean and hyper little creatures.
