Which specific berries are listed as dietary components for the White-Eyed Vireo during the fall and winter migration period?
Berries from the dogwood, wax myrtle, and wild grapes.
The specific fruits consumed by the White-Eyed Vireo are heavily influenced by the local flora available across its geographic range during the non-breeding seasons. For those found in areas associated with their breeding grounds or during the initial stages of fall transition, certain key plant sources are cataloged. These include the berries produced by dogwood trees, the fruit from wax myrtle shrubs, and the tendrils of wild grapes. While the text notes that birds further south or in their wintering grounds may consume fruits like sumac, poison ivy, pokeweed, and tropical *Bursera* fruits, dogwood, wax myrtle, and wild grapes are specifically highlighted as widespread components during the general fall/winter dietary shift preceding or during migration.
