The cuckoo-finch (Anomalospiza imberbis), also known as the parasitic weaver or cuckoo weaver, is a small passerine bird now placed in the family Viduidae with the indigobirds and whydahs. It occurs in grassland in Africa south of the Sahara. The male is mainly yellow and green while the female is buff with dark streaks. They lay their eggs in the nests of other birds.
The species was described in 1868 by the German ornithologist Jean Cabanis based on a specimen from East Africa, probably from the coast opposite Zanzibar. It was initially placed in the genus Crithagra but later moved to a genus of its own, Anomalospiza. The name of the genus means "anomalous finch" with spiza being a Greek word for finch. The specific name imberbis comes from Latin and means "beardless".
Its closest relatives are thought to be the indigobirds and whydahs of the genus Vidua. These birds are now usually considered to form a family, Viduidae. Previously they were treated as a subfamily, Viduinae, within either the estrildid finch family Estrildidae, or the weaver family Ploceidae.
The cuckoo-finch is a small finch-like bird, about 11–13 cm long. It has a short tail, large... Wikipedia →

With luck
About 10% of wildlife watchers report a Cuckoo Finch sighting in Nairobi National Park on a given day, based on 95 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 218th most-seen of the 371 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March–April, June–July and November–January
In those months about 10% of wildlife watchers report a Cuckoo Finch in Nairobi National Park on a given day, against under 5% in February, May and August–October, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Cuckoo Finch sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Cuckoo Finch sightings, Nairobi National Park has the highest daily chance: about 10%. Next come Kidepo Valley National Park (Uganda, about 10%) and Masai Mara National Reserve (Kenya, under 5%).
GBIF citizen-science records
It is estimated from how often the Cuckoo Finch is recorded against all the birds logged in Nairobi National Park (95 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.
