Magpie-lark (also known as Peewee, Mudlark, or Little Magpie)

This feather comes from the Magpie-lark, a bold black-and-white monarch flycatcher. Adult birds are roughly 30cm long with a piercing pale eye. They are famous for their coordinated 'duetting' songs and their unique bowl-shaped nests made of mud and grass. They are frequently seen walking on the ground with a rhythmic head-bobbing motion.

Distinctive bicolor pattern: the basal two-thirds is a clean white, while the distal third (tip) is a solid, deep black or dark charcoal. The transition between colors is sharp with a slight diagonal slant.

Tightly interlocked pennaceous barbs for the majority of the vane to provide aerodynamic lift. The base of the feather shows some plumulaceous (downy) barbs near the superior umbilicus.

Smooth and stiff with a slightly glossy finish on the black portion. The surface is streamlined for flight efficiency. The trailing edge is softer than the rigid leading edge.

Sharp bicolor contrast (white base, black tip), primary feather asymmetry, and a size corresponding to a large songbird.

Ubiquitous across various environments including urban parks, gardens, wetlands, grasslands, and riparian woodlands. They are famously adapted to human-altered landscapes.

Resident throughout mainland Australia (except for the driest deserts) and southern New Guinea. They do not migrate but may move locally following rain.

Insectivorous predator. They play a vital role in controlling invertebrate populations. They are also known to be aggressive defenders of their territory, often chasing away much larger birds.

Australian Magpie feathers (usually larger, differently patterned), Pied Butcherbird feathers (different color distribution), and Australian White Ibis (much larger and different texture).

Despite the name, they are not closely related to true Magpies or Larks; they are actually large monarch flycatchers. They are one of the few birds in the world that perform synchronized singing in a perfectly timed duet to defend territory.

Excellent condition. The vane is intact without significant fraying or fault bars, suggesting it was recently molted or lost from a healthy bird.
