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.

Likely
About 40% of wildlife watchers report a Spur-winged Goose sighting in Kigali on a given day, based on 423 verified sightings from GBIF citizen-science data. It is the 28th most-seen of the 244 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
December
In that month about 60% of wildlife watchers report a Spur-winged Goose in Kigali on a given day, against about 10% in May, the lowest month.
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.
Yes
Of the 9 cities where we can rate Spur-winged Goose sightings, Kigali has the highest daily chance: about 40%. Next come Durban (South Africa, about 10%) and Cape Town (South Africa, about 10%).
Same family: Anatidae
The closest relatives of the Spur-winged Goose that you can see in Kigali (family Anatidae, Ducks, Geese, and Swans) are White-faced Whistling Duck (about 20%) and Yellow-billed Duck (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 Kigali (423 verified sightings), 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.
