How to Identify New Zealand Fantail Feathers

What New Zealand Fantail's Feathers Look Like

The fantail (piwakawaka) is one of New Zealand's smallest and most recognizable birds, and its most distinctive feathers by far are the tail feathers, which make up its namesake fan. Tail feathers are unusually long relative to the tiny body — 6-8 cm — dark brown-black at the base with broad white tips and white outer edges on the common "pied" morph; a rarer all-dark "black" morph (more frequent in the South Island) instead shows a sooty black tail with little or no white. Body feathers are tiny (1.5-3 cm), with a gray-brown back, a black band across the upper breast, rufous-orange wash on the flanks and rump in the pied morph, and a whitish throat and belly. A short white or pale eyebrow-stripe feather is sometimes findable near the head. Flight feathers are small and rounded, 4-5 cm, plain grayish brown with little pattern; the tail is by far the more diagnostic feather type. Shafts are pale on the white-tipped tail feathers and grayish brown elsewhere.

Step-by-Step: Is This Feather From a New Zealand Fantail?

• Check the size first. Anything longer than about 8 cm is too big; this is a tiny bird.
• Look for a broad white tip on a dark brown-black tail feather with white edging — the single best diagnostic sign for the common pied morph.
• Consider the black morph if the tail feather is all sooty black with no white; more likely in South Island birds.
• Look for rufous-orange tinting on small body feathers, especially from the flank/rump area.
• Check for a black breast-band feather, dark and narrow, if you have body feathers.
• Rule out other tiny songbirds by the tail feather's proportionally long length relative to its narrow width.

Similar Species & How to Tell Them Apart

Grey Warbler, which shares habitat, has plain gray-olive tiny feathers with no white tail tips and a much shorter, unremarkable tail. Silvereye feathers are olive-green with a white eye-ring feather patch but a short, unpatterned tail lacking any white tip. Tomtit, found in similar forest, has bold black-and-white or yellow-and-black patterning concentrated on the body and a shorter, plain dark tail without white tips. The fantail's combination of a very long tail relative to body size, with a broad white terminal band, is essentially unmatched among New Zealand's small forest songbirds.

Where & When You'll Find Them

Fantails are widespread and confiding across forest, scrub, and garden habitats throughout New Zealand, often approaching people and pets as they hawk for insects. They breed multiple times per season and molt mainly after the breeding season ends, from late summer into autumn (February through April), meaning small, fresh body and tail feathers commonly turn up on garden paths, decks, and forest tracks during this period. Because fantails actively flick and fan their tails while hunting, worn or damaged tail feathers are also not unusual finds even outside the main molt period.
