The thick-billed weaver (Amblyospiza albifrons), or grosbeak weaver, is a distinctive and bold species of weaver bird that is native to the Afrotropics. It belongs to the monotypic genus Amblyospiza and subfamily Amblyospizinae.
They have particularly strong mandibles, which are employed to extricate the seeds in nutlets and drupes, and their songs are comparatively unmusical and harsh. Their colonial nests are readily distinguishable from those of other weavers, due to their form and placement, and the fine strands used in their construction.
They habitually fan and flick their tails. The generic name Amblyospiza was coined by Carl Jakob Sundevall in 1850 and means "blunt, finch", referencing the very large bill, while the specific name albifrons refers white forehead of the males. The thick-billed weaver was formally described as Pyrrhula albifrons in 1831 by the Irish zoologist and politician Nicholas Aylward Vigors from the collection of Henry Ellis, the specimens of which were attributed to Algoa Bay and environs in the Eastern Cape.

Possible
About 20% of wildlife watchers report a Grosbeak Weaver sighting in Arusha National Park on a given day, based on 122 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 94th most-seen of the 373 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report a Grosbeak Weaver in Arusha National Park on a given day, against about 10% in February, May–June, August–September and December, the lowest months. That is one of Arusha National Park's wettest months, with about 440 mm of rain against 65 mm in September.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Grosbeak Weaver sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 28
Of the 28 parks where we can rate Grosbeak Weaver sightings, Arusha National Park ranks 5th at about 20%. The best odds are in Kibale National Park (Uganda, about 40%), iSimangaliso Wetland Park (South Africa, about 30%) and Semuliki National Park (Uganda, about 30%).
Same family: Ploceidae
The closest relatives of the Grosbeak Weaver that you can see in Arusha National Park (family Ploceidae, Weavers and Allies) are Baglafecht Weaver (about 50%), Taveta Golden-Weaver (about 30%) and Yellow-rumped Widowbird (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Grosbeak Weaver is recorded against all the birds logged in Arusha National Park (122 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.
