Where there are willows, cottonwoods or sycamores in the Sonoran Desert there are likely to be Yellow Warblers. These are the rare riparian habitats that support so many of the unique species in the desert. Warblers are largely insectivorous and their principal foods are caterpillars and other arthropods cleaned from foliage. During the winter months these migrants return to the tropics where insect prey remain available.
