Description

A medium-sized thrush; males are iconic for their jet-black plumage and bright orange-yellow eye-rings and bills. Females and juveniles exhibit the more subtle, warm brown tones seen in this feather, often with slight mottling on the breast.

Colour & Pattern

Uniformly dark rufous-brown to sooty blackish-brown; the color is consistent with a female or juvenile Eurasian Blackbird, lacking the deep jet-black of an adult male.

Barb Structure

Transitioning from plumulaceous (downy) at the base to pennaceous (firm and interlocked) at the distal two-thirds; barbs are relatively loose at the edges, indicating a soft body feather.

Rachis & Barb Pattern

The rachis is thin, semi-translucent at the calamus, darkening to a medium brown throughout the vane; barbs are densely packed but fine.

Texture & Surface

Velvety and soft to the touch; the distal portion has a slight matte finish with no significant iridescence, suitable for blending into woodland floor shadows.

Feather Placement

Likely originated from the flank or lower breast; the proportion of downy base to firm tip is characteristic of insulating body feathers.

Key Features

Uniform warm brown coloration without distinct banding; small size; specific ratio of plumulaceous base to pennaceous tip indicating passerine origin.

Habitat

Woodlands, gardens, parks, and hedgerows; highly adaptable to both rural and urban environments with soft soil for foraging.

Geographic Range

Native to Europe, Asia, and North Africa; introduced and widespread in Australia and New Zealand.

Ecological Role

Omnivorous ground-forager; plays a vital role in seed dispersal and controlling invertebrate populations (earthworms, beetles).

Similar Species

Song Thrush (Turdus philomelos) feathers are usually lighter with distinct spotting on the distal end; Common Starling (Sturnus vulgaris) feathers would show iridescent tips or white triangular spots.

Interesting Facts

The Eurasian Blackbird is famous for its melodious, fluted song, often heard at dawn and dusk. It was one of the first birds to adapt successfully to night-time singing in urban areas to avoid noise pollution.

Cultural Significance

Well-known in European folklore and music (notably the Beatles' 'Blackbird'). Historically, they were occasionally kept as cage birds for their song.

Field Identification Tips

Look for these feathers near garden lawns or woodland edges where birds 'dust bathe' or preen; they are most frequently found during the post-breeding molt in late summer.

Condition Notes

Good condition; the distal barbs show minimal fraying, suggesting it was likely lost during a natural molt rather than through predation or environmental stress.
