I thoroughly enjoy watching the Verdins who come into our backyard in the springtime. They arrive early in the year. I'd never heard of these sweet little birds until I came to Tucson. Sometimes they are quite yellow, sometimes more orange. I spent about twenty minutes one morning recently, trying to get some good shots of this little fellow as he flitted through a large mesquite tree.
I wrote about Verdins in a previous post. In that post, I photographed them with a 100 mm. prime lens (no image stabilization). These were photographed at 300 mm. with an image-stabilized zoom lens.
