I think this is the first time I have seen a hummingbird picture quite like this one. This little one (I believe it is a black-chinned hummingbird) was feeding on the Wisteria blossoms hanging from the trellis in our backyard. The green you see through it's wing is actually part of the Wisteria plant. My wife has some MAD skills!
We have seen a lot of hummingbirds this year in our neighborhood. Every time one comes to the feeder hanging from our kitchen window, whoever is nearby will stop and just watch for a while. They truly are amazing. They are so small, with their hearts beating at about 1200 beats per minute. And they flit around our yard with such acrobatic zeal that you cannot help but smile.
