The Yellow-rumped Warbler is one of the most adaptable and widespread warblers in North America and a familiar sight in Arizona during migration and winter. Its bright yellow rump, sides, and crown are diagnostic, and it often flocks in open woodlands, city parks, and riparian groves. Arizona hosts both the “Audubon’s” and “Myrtle” subspecies, distinguishable by throat color. Unlike most warblers, Yellow-rumpeds can digest waxes from bayberries and junipers, allowing them to overwinter farther north than others. They feed on insects in warmer months but switch to berries in winter.
