The Palm Warbler can be most easily recognized by the tail-wagging habit that shows off its yellow undertail.
They forage on the ground much more than other warblers, sometimes flying to catch insects.
This is one of only three Dendroica warblers (Kirtland's and Prairie are the others) to incessantly bob its tail.
A group of palm warblers are collectively known as a "reading" of warblers.
