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

This is a tail feather from a Magpie-lark, a bold black-and-white monarch flycatcher. The bird grows to about 25-30cm and is famous for its complex antiphonal duets and its bowl-shaped mud nests. Both sexes share the black and white motif, but males have a black throat while females have a white throat

Distinctive bicoloration: the basal two-thirds are a deep, matte black-sooty charcoal, while the distal third (tip) is a stark, clean white. This high-contrast pattern is a diagnostic trait for the species

Pennaceous and tightly interlocked along the distal half; plumulaceous (downy) at the very base for insulation; barbs appear intact with minor fraying

The rachis is dark/black through the pigmented section and transitions to translucent or pale white at the tip; moderate thickness providing rigidity for flight

Smooth, somewhat stiff, and matte; the white tip has a slightly softer visual texture compared to the melanin-rich black portion

Tail (Retrix); indicated by the thickness and straightness of the rachis and the specific distribution of the white tip

The sharp, clean demarcation between the black base and the white tip on an asymmetrical tail feather is the primary identifier

Varied: urban parks, gardens, wetlands, and open grasslands; requires bare soft ground for mud-nesting

Resident across mainland Australia and southern New Guinea; essentially sedentary but moves toward water during dry seasons

Predatory insectivore; helps control lawn grubs and garden pests. They are territorial and will aggressively defend their nests from intruders

Australian Magpie feathers (much larger, different white placement), Pied Currawong feathers (white at base, not the tip), Willie Wagtail (smaller, mostly black)

Magpie-larks are one of the few birds in the world that sing in perfectly synchronized duets, where the male and female alternate notes so quickly it sounds like a single bird

Historically known as 'Peewee' in Australian folklore due to its call. Not widely used in commercial trade, but often found by children in suburban backyards

Look for these in late summer and autumn during the post-breeding molt, especially around parklands and sporting ovals where the birds forage

Good condition; slight mechanical wear (fraying) on the trailing edge suggests it was naturally molted late in the season
