About Rhinoceros Auklet
The rhinoceros auklet (Cerorhinca monocerata) is a seabird and a close relative of the puffins. It is the only extant species of the genus Cerorhinca. Given its close relationship with the puffins, the common name rhinoceros puffin has been proposed for the species.From Wikipedia via iNaturalist — article, CC BY-SA.
