This small, acrobatic bird is often seen upside down on a tree trunk or branch as it is forging for insects beneath the bark. It has a rather unique appearance as well – a white head with black cap, blue-grey top and white belly. Females look nearly the same, substituting a grey cap for the black one.

They are year round inhabitants and in winter will be seen in mixed flocks with chickadees and tufted titmice. This is a survival strategy that small birds use to enhance their safety and increase their chances of finding food.

Their song is a nasal, repetitious “wha wha wha”. Listen below.
