This is an environmental shot of a Carolina Wren. Carolina Wrens are small scrappy birds that remain in their territories year round, and vigorously defend them. Probably the most interesting aspect of their behavior is the fact that they build decoy nests to confuse predators. While one of the pair sits on one of possibly many fake nests, the other is sometimes relatively far away, sitting on the more hidden real nest.
