Common

This small songbird is a cavity nester. It arrives early in the spring and prefers old-growth cottonwood trees, and willow trees where it actively gleans in the foliage for insects. In spring the males sing incessantly which makes finding them easier � particularly if the deciduous trees have already leaved out.
