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 →

With luck
About 10% of wildlife watchers report a Rifleman sighting in Egmont National Park on a given day, based on 62 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 35th most-seen of the 46 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Rifleman is recorded against all the birds logged in Egmont National Park (62 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.
