In which avian Order is the Yellow-Eyed Penguin classified alongside all other penguins?
Answer
Sphenisciformes
The taxonomic hierarchy places the Yellow-Eyed Penguin within the Order Sphenisciformes. This order is specifically dedicated to penguins, grouping all members of the penguin family tree together at this rank. While Aves is the Class (birds) and Spheniscidae is the Family (all extant penguins), Sphenisciformes is the specific Order that defines the grouping of penguins, separating them from other bird orders. Chordata is the much broader Phylum to which all vertebrates belong.
