The Horned Puffin Fratercula corniculata is a pelagic, wing-propelled diving seabird (Charadriiformes, Pan-Alcidae) with an exclusively northern Pacific Ocean distribution. Horned Puffins are 36-41cm in length, with a wingspan of 56-58cm and a body mass of ~612g (del Hoyo et al., 1996). Fratercula corniculata is one of three living species of puffin in the Pacific Ocean basin (also see Tufted Puffin Fratercula cirrhata, and Rhinoceros Puffin Cerorhinca monocerata). A single extant species, the Atlantic Puffin Fratercula arctica, is endemic to the Atlantic Ocean basin. Fossils of puffins are known from Pliocene locations along the eastern and western coasts of North America (Howard, 1971; Olson and Rasmussen, 2001; Smith et al., 2007; Smith, 2011a). Fossil remains of the puffin Cerorhinca minor indicate that these birds have inhabited the Pacific Ocean for at least the last five million years (i.e., since the Early Pliocene; Howard, 1971; Smith, 2011a). Furthermore, The Atlantic Ocean was inhabited by at least three species of puffins in the Early Pliocene (Smith et al., 2007).

Fratercula corniculata

Systematically, the Horned Puffin is a part of Pan-Alcidae (Aves, Charadriiformes), which includes auks, auklets, puffins, guillemots, murres, and murrelets. Phylogenetic analyses of morphological and molecular sequence data indicate that the Tufted Puffin and the Atlantic puffin are more closely related to one another than either is to the Horned Puffin (Strauch, 1985; Pereira and Baker, 2008; Smith 2011b; Smith and Clarke, 2015).

Similar to penguins in their behavior, alcids are diving birds that 'fly' underwater in pursuit of prey. Like many other alcids (e.g., murres and auks), Horned Puffins feed primarily on fish, but also supplement their diet with crustaceans and other invertebrates (del Hoyo et al., 1996). Horned Puffins spend most of their lives at sea, usually coming ashore only to breed. Puffins are monogamous and commonly breed along rocky shorelines in large colonies (del Hoyo, 1996). Puffins are the only alcids that are known to excavate burrows in which they raise their young and have an enlarged second toe that they use for that purpose (Strauch, 1985). The shape of the brain of puffins also differ from that of other pan-alcids; however the reason(s) for this difference have not yet been established (Smith and Clarke, 2012). For more information about the endocranial anatomy of the Horned Puffin and other Charadriiformes see Smith and Clarke (2012) and renderings of the cranial endocast under 'Additional Imagery.'

About the Species

This specimen, a female, was salvaged between Cape Douglas and Chignik on the Alaskan Peninsula from the Exxon Valdez Oil Spill on 7 September 1989. It was made available to the University of Texas High-Resolution X-ray CT Facility for scanning by Dr. N. Adam Smith of the Field Museum of Natural History. Funding for scanning and image processing was provided by an NSF grant (DEB 0949897) to Julia Clarke and N. Adam Smith and by The Jackson School and the High-Resolution X-ray CT Facility.

About this Specimen

This specimen was scanned by Matthew Colbert on 4 August 2009 along an oblique coronal axis for a total of 1782 slices. Each 1024 x 1024 pixel slice is 0.04459 mm thick with an interslice spacing 0.04459 mm and a field of reconstruction = 42 mm.
