The thick-billed seedeater (Crithagra burtoni) is a species of finch in the family Fringillidae. It is native to the Western High Plateau and Bioko, the Albertine rift montane forests and the East African montane forests.
The thick-billed seedeater was formerly placed in the genus Serinus but phylogenetic analysis using mitochondrial and nuclear DNA sequences found that the genus was polyphyletic. The genus was therefore split and a number of species including the thick-billed seedeater were moved to the resurrected genus Crithagra. Wikipedia →

Rare
Under 5% of wildlife watchers report a Thick-billed Seedeater sighting in Arusha National Park on a given day, based on 28 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 212th most-seen of the 373 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Thick-billed Seedeater in Arusha National Park on a given day, against under 5% in June–August and December–March, the lowest months. That is one of Arusha National Park's driest months, with about 65 mm of rain against 440 mm in April.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Thick-billed Seedeater sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 8
Of the 8 parks where we can rate Thick-billed Seedeater sightings, Arusha National Park ranks 6th at under 5%. The best odds are in Aberdare National Park (Kenya, about 30%), Bwindi Impenetrable National Park (Uganda, about 20%) and Nyungwe National Park (Rwanda, about 20%).
Same genus: Crithagra
The closest relatives of the Thick-billed Seedeater that you can see in Arusha National Park (genus Crithagra, African Seedeaters, Serins, Canaries, and Citrils) are Southern Citril (about 20%), Streaky Seedeater (about 20%) and Yellow-fronted Canary (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Thick-billed Seedeater is recorded against all the birds logged in Arusha National Park (28 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.
