Rhinoceros Auklet
15. Cerorhinca monocerata. 11 inches.
These birds have a much smaller bill than the Puffins; in the summer plumage there is a small horn at the base of the bill from which it is given its name. These birds do not stand upright as do the Puffins; but sit upon their tarsus.
Nest.—A single egg is laid in either burrows or in crevices of the rocks, usually without any attempt at nest making (2.70 × 1.80).
Range.—Coast and islands of the northern Pacific. Breeds from Oregon to northern Alaska.
