Anas discors and Anas americana
Aix sponsa, known as the wood duck, is more closely related to Anas acuta (the northern pintail) than to Anas cyanoptera (the white-cheeked pintail). Both Aix and Anas belong to the family Anatidae, but their evolutionary lineages diverged at different points. Specifically, Aix is part of a separate genus, indicating a closer relationship with Anas acuta within the broader context of dabbling ducks. However, all three species share a common ancestry within the duck family.
