Turquoise-browed Motmot (or Guardabarranco)

This signature tail feather belongs to the Turquoise-browed Motmot, a striking medium-sized Neotropical bird known for its brilliant turquoise-blue brow, rufous back and belly, and dramatic racket-tipped tail. The bird frequently twitches its tail side-to-side like a pendulum when perched, serving as a signal to predators and potential mates.

Brilliant iridescent deep metallic blue, turquoise, and teal on the upper vane transition; dark blackish-blue shaft; iridescent violet-blue and deep azure on the terminal racquet paddle with black tips

Pennaceous structure on both upper vane and racquet tip; barbs on the central shaft section are weakly attached and naturally shed during preening to form the bare wire

Smooth, glossy, and highly iridescent due to structural coloration; stiff and springy rachis

Unique racquet-tail configuration with long bare central shaft; brilliant iridescent turquoise and violet-blue terminal paddle with a dark tip

Open tropical woodlands, dry scrub forest, gallery forests, forest edges, plantations, and secondary growth

Mesoamerica, extending from southern Mexico (Yucatan Peninsula) south through Guatemala, Belize, El Salvador, Honduras, Nicaragua, and northwestern Costa Rica

Perch-and-swoop predator consuming insects, small lizards, and fruit; acts as a seed disperser and maintains insect population levels in dry tropical forest ecosystems.

Other Motmot species such as the Lesson's Motmot (Momotus lessonii) or Broad-billed Motmot (Electron platyrhynchum), but Eumomota superciliosa features distinct brightly colored turquoise-violet racquets and longer bare shafts.

The tail rackets are formed because the barbs along the mid-shaft are weakly attached and fall off naturally or are preened off shortly after molting; the pendulum tail-wagging behavior is an pursuit-deterrent signal informing predators that they have been detected.

Good condition; structural iridescence remains vivid; minor vane separation/fraying on lower barb margins typical of molted tail feathers
