The
genus Fratercula was introduced by the French zoologist
Mathurin Jacques Brisson in 1760 with the
Atlantic puffin (
Fratercula arctica) as the
type species. The name
Fratercula is
Latin for "
friar" from the word
fraterculus "little brother", because the puffin's black and white plumage resemble robes worn by
monks. The genus contain three species. The
rhinoceros auklet (
Cerorhinca monocerata) has sometimes been included in the genus
Fratercula, and some authors place the tufted puffin in the genus
Lunda. The puffins and the rhinoceros auklet are closely related, together composing the subfamily Fraterculini. Fossils from North Carolina were originally thought to have been of two
Fratercula species, but were later reassigned to one
Fratercula, the tufted puffin, and a
Cerorhinca species. Another extinct species,
Dow's puffin (
Fratercula dowi) was found on the
Channel Islands of California until the
Late Pleistocene or early
Holocene. in
Seattle, Washington The Fraterculini are thought to have originated in the Pacific, primarily due to their greater diversity there; there exists only one extant species in the Atlantic, compared to two in the Pacific. This species has shown some significant signs of animal intelligence. In January 2020, some researchers reported that, Atlantic puffins were seen using sticks as a tool to scratch themselves. The Fraterculini fossil record in the Pacific extends at least as far back as the middle
Miocene, with three fossil species of
Cerorhinca, and material tentatively referred to that genus, in the middle Miocene to late
Pliocene of southern California and northern Mexico. Although there are no records from the Miocene in the Atlantic, a re-examination of the North Carolina material indicated that the diversity of puffins in the early Pliocene was as great in the Atlantic as it is in the Pacific today. This diversity was achieved through influxes of puffins from the Pacific; the later loss of species was due to major oceanographic changes in the late Pliocene due to closure of the Panamanian Seaway and the onset of severe glacial cycles in the North Atlantic.
