  2. Vocal Prowess

  3. Biotic Invasion

  4. Superb Coloration Cedar Waxwing tail tips, normally yellow, can be partly orange (as seen here) owing to the incorporation into developing tail feathers of rhodoxanthin, a red pigment found in Tartarian Honeysuckle berries that waxwings frequently consume during molt. This adult must have increasingly fed on honeysuckle berries as the molt of its tail proceeded from central tail feathers to outer ones. Note also waxy tips to wing feathers (secondaries), which give the species its name. Wax-like wing tips are feathers with fused terminal barbs
