The rufous-tailed weaver (Histurgops ruficauda) is a species of songbird found in Tanzania. It is included in the weaver family (Ploceidae), but many authors included it in the Old World sparrow family Passeridae when Old World sparrows were separated from the weavers proper. It is placed in the monotypic genus Histurgops.
It is an endemic breeder in Tanzania, but vagrants occur in Kenya too. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Rufous-tailed Weaver is recorded against all the birds logged in Lake Manyara National Park (20 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.
