The following is a list of tautonyms : zoological names of species consisting of two identical words (the generic name and the specific name have the same spelling). Such names are allowed in zoology, but not in botany, where the two parts of the name of a species must differ (though differences as small as one letter are permitted, as in cumin, Cuminum cyminum).

The Eurasian oystercatcher also known as the common pied oystercatcher, or just oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It has striking black and white plumage, a long straight orange-red bill, red eyes and relatively short dull pink legs. The sexes are similar in appearance but the bill of the female is longer than that of the male.
The Eurasian treecreeper or common treecreeper is a small passerine bird also known in the British Isles, where it is the only living member of its genus, simply as treecreeper. It is similar to other treecreepers, and has a curved bill, patterned brown upperparts, whitish underparts, and long stiff tail feathers which help it creep up tree trunks. It can be most easily distinguished from the similar short-toed treecreeper, which shares much of its European range, by its different song.
Noctua is a genus of moths. They have dull, cryptic forewings and often very bright hindwings. These are hidden under the forewings when the moths rest, leading to their common name of yellow underwings. They are not particularly closely related to the "true" underwing moths (Catocala) though, apart from both being Noctuoidea. They are good fliers.
