*edit- i guess my post was so offtopic it was made a topic on its own. This is directed at andrew, and i am responding to him in this...
Oh not at all. I know for a fact that Arizona has more hummingbird species than the entire rest of the united states combined. Mostly Mexican species reaching the extreme northern limits of their habitat. Andrew do you get any of these Arizona beauties where you live?There are definatly lots of hummingbirds! I was unaware one was any different than the other LOL their nests sure are neat though! And to watch them sit on the nest with just a beak hanging over (or 3 or 4 once the babies are bigger) is quite the site!
We only get Ruby-thoats through migration here in eastern SD. Dont ask me how they find food, flowers cannot be found for miles on end. It would be nice to have the variety that you do down there. We have the upper hand on wood warblers, finches, and blackbirds but they just are not the same!
