The spur-winged goose (Plectropterus gambensis) is a large, Sub-Saharan African waterbird in the family Anatidae, which includes geese and shelducks. However, P. gambensis developed unique environmental adaptations, which resulted in the evolution of several anatomical features that are not shared with other anatids; thus, the species has been classified one step further into its own subfamily, the Plectropterinae.
Adults are 75–115 cm (30–45 in) long, and weigh an average of 4–6.8 kg (8.8–15.0 lb) (rarely up to 10 kg (22 lb)), with ganders (males) being noticeably larger than the geese. The wingspan can range from 150 to 200 cm (59 to 79 in). One source claims the average weight of males is around 6 kg (13 lb) and the weight of females is around 4.7 kg (10 lb). However, 11 individuals that were banded in South Africa, were found to average only 3.87 kg (8.5 lb), with a range of 2.4 to 5.4 kg (5.3 to 11.9 lb). Another South African-based study found 58 males weighing an average of 5.52 kg (12.2 lb) and measuring 98.1 cm (38.6 in) in total length; meanwhile, 34 females averaged 3.35 kg (7.4 lb) in weight and 84.2 cm (33.1 in) in total length.

Rare
Under 5% of wildlife watchers report a Spur-winged Goose sighting in Nairobi National Park on a given day, based on 31 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 290th most-seen of the 371 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
April
In that month about 10% of wildlife watchers report a Spur-winged Goose in Nairobi National Park on a given day, against under 5% in May to March, the lowest months. That is one of Nairobi National Park's wettest months, with about 180 mm of rain against 15 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Spur-winged Goose sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
35th of 38
Of the 38 parks where we can rate Spur-winged Goose sightings, Nairobi National Park ranks 35th at under 5%. The best odds are in Liwonde National Park (Malawi, about 70%), Gonarezhou National Park (Zimbabwe, about 60%) and Chobe National Park (Botswana, about 50%). All parks ranked.
Same family: Anatidae
The closest relatives of the Spur-winged Goose that you can see in Nairobi National Park (family Anatidae, Ducks, Geese, and Swans) are Egyptian Goose (about 70%), White-faced Whistling Duck (about 20%) and Red-billed Teal (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Spur-winged Goose is recorded against all the birds logged in Nairobi National Park (31 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.
