Arnot's chat (Myrmecocichla arnotti), also known as the white-headed black-chat, is a species of bird in the chat and flycatcher family Muscicapidae. The species is found in southern Africa from Rwanda and Angola to South Africa.
Arnot's chat was formally described and illustrated in 1869 as Saxicola arnotti by English clergyman and ornithologist Henry Baker Tristram based upon a specimen collected at the Victoria Falls in modern-day Zimbabwe. Tristram wrote that he named the species after the collector, a Mr. Arnott, but the man was actually named David Arnot. For this reason, it was suggested in 1965 that the name should be spelled arnoti instead. However, since there is no evidence in Tristram's original paper that the name was misspelled, the rules of the International Code of Zoological Nomenclature mandate that the spelling arnotti should be maintained. Arnot's chat is now placed in the genus Myrmecocichla that was introduced in 1851 by the German ornithologist Jean Cabanis. Along with the white-fronted black chat this species is sometimes separated into the genus Pentholaea.

Rare
Under 5% of wildlife watchers report a White-headed Black-Chat sighting in Kigali on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 209th most-seen of the 244 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a White-headed Black-Chat in Kigali on a given day, against under 5% in November to September, the lowest months.
Only Kigali, in our data
Kigali is the only city on Wallace's Line with enough records to rate White-headed Black-Chat sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Muscicapidae
The closest relatives of the White-headed Black-Chat that you can see in Kigali (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are White-browed Robin-Chat (about 80%), Swamp Flycatcher (about 30%) and African Stonechat (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-headed Black-Chat is recorded against all the birds logged in Kigali (13 verified sightings), 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.
