Hartlaub’s Duck

The Hartlaub’s Duck (Pteronetta hartlaubii) is a dark chestnut-colored duck of African forests. Formerly included in the paraphyletic “perching duck” assemblage, it was later moved to the dabbling duck assemblage.¬†However, it is fairly distinct from the “typical” dabbling ducks, and is placed in the mono-typic genus Pteronetta to reflect this.

Breeding Season: – Unknown but most likely during the rainy season.

Eggs: – 7 to 12 (creamy-white color).

Notes: – The Hartlaub’s Duck was considered a perching duck but is now placed on its own in the genus Pteronetta. Little is known about this duck in the wild and no wild nests have been found. It most likely nests in tree hollows and perches in trees. This duck is named after the German naturalist Gustav Hartlaub. This species is considered near-threatened and has declined due to deforestation causing loss of habitat.

The different types of wild ducks can be grouped into puddle, aka “dabbling” and diving ducks. The dabblers mostly feed in smaller bodies of shallow water or along shorelines, where they are able to tip their bodies forward to reach their food on the bottom. There are divers who feed in deeper water where they dive and pursue their quarry. Some of these birds, the Harlequin Duck for example, actually dives to the bottom of fast-flowing waters and feeds on life forms attached to rocks.
