Magpie-Lark (also known as Pee-wee, Mudlark, or Little Magpie)

These feathers belong to a medium-sized bird (25-30 cm) with bold black-and-white plumage. The species is famous for its 'Mudlark' name because it builds deep bowl-shaped nests of mud and grass. They have pale eyes and a complex duetting song where pairs alternate notes precisely.

Distinctly bicolored. The proximal two-thirds to three-quarters is a clean white, while the distal tip is a deep brownish-black or charcoal black. The transition is sharp but slightly angled across the vane.

Mostly pennaceous and tightly interlocked along the distal (dark) portion; plumulaceous and loose at the proximal (white) base. The barbs are relatively stiff for a passerine.

The surface is matte to slightly glossy on the dark tip. The texture is smooth and firm, providing the necessary rigidity for balance and steering during flight.

The sharp contrast between the long white base and the dark 'dipped' tip is diagnostic for Grallina cyanoleuca tail feathers, along with the relatively small size compared to a Pied Currawong or Australian Magpie.

Highly adaptable; found in urban parks, gardens, wetlands, grasslands, and riparian woodlands with access to soft mud for nest building.

Common throughout mainland Australia (except for the driest deserts) and southern New Guinea. Highly sedentary but highly mobile within its range.

Insectivorous ground-feeder. They play a significant role in controlling populations of lawn grubs and garden insects. They are highly territorial indicators of local environmental health.

Australian Magpie (feathers are much larger and patterned differently), Pied Currawong (larger with white only at the absolute base and tip), Willie Wagtail (much smaller, tail feathers are mostly black).

The Magpie-lark is one of the few bird species where males and females perform perfectly synchronized duets to defend their territory. They are not actually magpies or larks, but a type of large monarch flycatcher.

Fair to Good. Some mechanical fraying is visible along the edges of the white barbs (splitting), which is common in ground-foraging birds where feathers rub against vegetation.
