Yellow-billed Duck (Anas undulata)
![]() Other names: Afrikaans: Geelbekeend German: Gelbschnabelente French: Canard à bec jaune Dutch: Geelbekeend The Yellow-billed Duck, Anas undulata, is a dabbling duck which is an abundant resident breeder in southern and eastern Africa. This duck is not migratory, but will wander in the dry season to find suitable waters. It is highly gregarious outside the breeding season and forms large flocks. These are Mallard-sized mainly grey ducks with a darker head and bright yellow bill. The wings are whitish below, and from above show a white-bordered green speculum. Sexes are similar, and juveniles are slightly duller than adults. The north-eastern race is darker and has a brighter bill and blue speculum. It is a bird of freshwater habitats in fairly open country and feeds by dabbling for plant food mainly in the evening or at night. It nests on the ground in dense vegetation near water. The clutch numbers between six and twelve eggs. The male has a Teal-like whistle, whereas the female has a mallard-like quack. The Yellow-billed Duck is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. |

Very common bird in the Western Cape.
I have heard from a few people that there has been a big problem in the inbreeding beween the yellowbilled and Mallard Ducks. Does anybody have some more info on the breeding of these two birds? |

I spotted a male Mallard Duck (R923 - Anas platyrhynchos), which is actually an alien invader in the large dam at the Brakfontein Picnic Spot (S30.51578 E26.27489) in Tussen-die-Riviere NR near Bethulie yesterday. It is quite concerning as this invader is a threat to the Yellow-billed duck (R104 - Anas undulata). The dam is a known breeding spot for the Yellow-billed, and the invader looked quite at home there.
Unfortunately no pic, batteries were flat |
