A rank the corpus never prints, carrying two English forms that name no clade beneath it.

birds of prey (1-252, tabooed by the Reindeer Chukchee) is polyphyletic in the plainest way: hawks, eagles and falcons are not each other's closest relatives, and owls are further still — Strix nyctea, the one raptor the chapter names in Latin, is the snowy owl the same sentence says is eaten. The taboo and its exception therefore cannot both hang from one group.

eagle (1-253, "as the eagle and the raven. To kill the former would bring a dense fog") is polyphyletic within Accipitridae, and the page names no species. The white-tailed eagle and the golden eagle both occur in the country; nothing here says which, or whether the distinction is one Bogoras's informants drew.

Both sit at this rank as the coarsest honest placement. Corvus corax, the raven of the same sentence, needs no such treatment — it is one bird.
