AI-generated identification · may be incorrectFamily: Monarchidae (Monarch Flycatchers)
- Shape
- Elongated and slightly tapered; essentially symmetrical, which is characteristic of inner or central tail feathers in this species. Rounded tips with a slight distal point.
- Size
- Approximately 12-15 cm in length. This is consistent with the standard tail length of an adult Magpie-lark, where tail feathers typically range between 10 and 16 cm.

Description
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.
Colour & Pattern
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.
Barb Structure
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.
Rachis & Barb Pattern
The rachis is thick and rigid at the base, transitioning from white in the light section to dark in the pigmented tip. Barbs are densely packed, maintaining a smooth vane surface.
Texture & Surface
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.
Feather Placement
Tail (Rectrices). The straightness of the rachis and the length-to-width ratio strongly suggest tail feathers rather than secondary wing feathers.
Key Features
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.
Habitat
Highly adaptable; found in urban parks, gardens, wetlands, grasslands, and riparian woodlands with access to soft mud for nest building.
Geographic Range
Common throughout mainland Australia (except for the driest deserts) and southern New Guinea. Highly sedentary but highly mobile within its range.
Ecological Role
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.
Similar Species
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).
Interesting Facts
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.
Cultural Significance
Well-known in Australian folklore and suburban culture as the 'Pee-wee' (named for its call). Historically not used in millinery but is a frequent subject in Australian art and children's nature stories.
Field Identification Tips
Look for these feathers under large gum trees or near suburban parks near water sources. They are often found in pairs during the post-breeding molt in late summer and autumn.
Condition Notes
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.
