What are the two living species comprising the Genus Aix?

Answer

Aix sponsa and Aix galericulata

The Genus *Aix* is remarkably small, containing only two recognized extant species, which signifies a highly specialized evolutionary path compared to other waterfowl genera, such as *Anas*. The first species is *Aix sponsa*, the Wood Duck, endemic to North America. The second species that shares this genus designation is the Mandarin Duck, scientifically known as *Aix galericulata*, which is native to East Asia. The commonality linking these two geographically separated species, justifying their placement together in the *Aix* genus, is their profound reliance on wooded habitats and their obligatory behavior of nesting inside tree cavities, contrasting sharply with many other members of the Order Anseriformes.
