Why are traditional mixed seed feeders often ignored by most warbler species?
Answer
Warblers are generally not seed eaters
The fundamental dietary classification for the majority of warbler species is insectivore, meaning their natural forage consists overwhelmingly of small arthropods, caterpillars, and occasionally fruit lipids when migrating. Seed consumption is not a characteristic behavior for this group, and therefore, traditional feeders containing sunflower seeds, millet, or mixed grains do not fulfill their specific nutritional requirements or match their innate foraging instincts. This lack of interest contrasts with birds specifically adapted for granivory.
