The rifleman was described by Anders Sparrman in 1787 based on a bird collected in Queen Charlotte Sound in the Marlborough Sounds of New Zealand's South Island. He originally placed it in the nuthatch genus Sitta. Frédéric de Lafresnaye placed it in its own monotypic genus Acanthisitta in 1842. The name Acanthisitta is a portmanteau of the thornbill genus Acanthiza and the genus Sitta.
The rifleman is named after a colonial New Zealand regiment because its plumage drew similarities with the military uniform of a rifleman. The rifleman is New Zealand's smallest endemic bird, with fully grown adults reaching around 7 to 9 cm (2.8–3.5 in) in length. Male birds typically weigh around 6 g (0.21 oz), females 7 g (0.25 oz). The bill of the female is also... Wikipedia →

Likely
About 60% of wildlife watchers report a Rifleman sighting in Arthur's Pass National Park on a given day, based on 858 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 48 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
January, March and June
In those months about 80% of wildlife watchers report a Rifleman in Arthur's Pass National Park on a given day, against about 40% in July and October, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Rifleman sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Rifleman sightings, Arthur's Pass National Park has the highest daily chance: about 60%. Next come Aoraki Mount Cook National Park (New Zealand, about 50%) and Rakiura National Park (New Zealand, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Rifleman is recorded against all the birds logged in Arthur's Pass National Park (858 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
