The green hylia (Hylia prasina) is a monotypic genus widespread in tropical Africa, where it mostly inhabits the understory and mid-stratum of moist forest. It is a canopy insectivore which had been tentatively placed within the family of Cettiidae warblers, but in 2019 its assignment to a new family, the Hyliidae, was strongly supported.
Hylia prasina is a monotypic songbird that has proven difficult to place within the phylogenetic tree. Connections between Hylia and other genera have been attempted by comparing DNA sequences, physical similarities and even behavioural characteristics. None of these links have been sufficiently proven to allow definite classification of the green hylia.
The green hylia belongs to the order Passeriformes and the superfamily Sylvioidea, however the classification at family level is under dispute. The species is often attributed to the family Cettiidae (bush warblers) along with Scotocerca, Erythrocercus, Tesia, Cettia and Abroscopus. Investigation into indels does not support a strong relationship between Hylia and the Cettiidae.
Anatomically, the green hylia has similarities to sunbirds and warblers. Characteristics shared with sunbirds... Wikipedia →

Possible
About 30% of wildlife watchers report a Green Hylia sighting in Kibale National Park on a given day, based on 569 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 35th most-seen of the 366 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
March and December
In those months about 50% of wildlife watchers report a Green Hylia in Kibale National Park on a given day, against about 20% in June and November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Green Hylia sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 8
Of the 8 parks where we can rate Green Hylia sightings, Kibale National Park ranks 2nd at about 30%. The best odds are in Semuliki National Park (Uganda, about 40%).
Same order: Passeriformes
The closest relatives of the Green Hylia that you can see in Kibale National Park (order Passeriformes, Perching Birds) are Common Bulbul (about 60%), Little Greenbul (about 50%) and Gray-headed Negrofinch (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green Hylia is recorded against all the birds logged in Kibale National Park (569 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.
