Common Starling Sturnus vulgaris
I don't know whether Common Starlings are treated with as much disdain in other parts of the world, as they sometimes are here, but they are stunningly beautiful birds if one takes the time to look at them closely.
They are, of course, an introduced species, and aggressively compete with native species for nesting cavities. But it is we who introduced them into North America and we should not now be maligning them for their success. They have become part of our avifauna and I always enjoy seeing them, especially when they enliven a sterile parking lot on a breezy winter's day.
