Shelley's greenbul (Arizelocichla masukuensis) or Shelley's bulbul, is a species of the bulbul family of passerine birds. It is found in east-central Africa. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical moist montane forests.
Shelley's greenbul was formally described in 1897 by the English ornithologist George Ernest Shelley based on specimens collected by the naturalist Alexander Whyte in the Misuku Hills of northern Malawi. Shelley placed the greenbul in the genus Andropadus and coined the binomial name Andropadus masukuensis where the specific epithet is from the type locality. Shelley's greenbul is now one of ten species placed in the genus Arizelocichla that was introduced in 1905 by the American ornithologist Harry C. Oberholser.

Rare
Under 5% of wildlife watchers report a Shelley's Greenbul sighting in Nyungwe National Park on a given day, based on 39 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 153rd most-seen of the 252 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
December and January
In those months about 10% of wildlife watchers report a Shelley's Greenbul in Nyungwe National Park on a given day, against under 5% in February to November, the lowest months. Those are among Nyungwe National Park's wettest months, with about 470 mm of rain a month against 30 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Shelley's Greenbul sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Shelley's Greenbul sightings, Nyungwe National Park ranks 2nd at under 5%. The best odds are in Bwindi Impenetrable National Park (Uganda, about 10%).
GBIF citizen-science records
It is estimated from how often the Shelley's Greenbul is recorded against all the birds logged in Nyungwe National Park (39 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.
