Anabernicula (SciiFii)

Sheldgeese (Anabernicula), also known as the American pygmy geese, are a genus of waterfowl that originally existed from the Pliocene to the Pleistocene and were once extinct, but has since been brought back from extinction by SciiFii and (re)introduced throughout the mainland North America, Channel Islands, and Hawaii to help boost biodiversity. Four species are known, the miniscule pygmy goose (Anabernicula minuscula), the California pygmy goose (Anabernicula gracilenta), the Oregon pygmy goose (Anabernicula oregonensis), and the robust pygmy goose (Anabernicula robusta). Despite the sheldgoose's goose-like appearance and build, it is actually a duck most closely related to the shelducks. All species of sheldgeese prefer to live in large aquatic habitats such as lakes and wetlands, and alongside many other types of waterfowl. The sheldgoose of all four species are herbivorous and mainly feed on grasses and aquatic vegetation. The conservation status of all known four species of sheldgoose is Least Concern due to successful conservation efforts, the sheldgoose's wide natural range and its tolerance to most of the human activities.
