How does the Mourning Warbler's foraging behavior typically differ from many other New World warblers during the season?

Answer

It nearly always forages low to the ground or in dense brush

Unlike many warblers that move through the mid-story or canopy, the Mourning Warbler maintains its preference for low cover, foraging near the ground, walking along branches, or hopping directly on the ground to find food.
