Synthliboramphus

Synthliboramphus is a small genus of seabirds in the auk family from the North Pacific. The genus name Synthliboramphus is from Ancient Greek sunthlibo, 'to compress', and rhamphos, 'bill'. 'Murrelet' is a diminutive of 'murre', a word of uncertain origins, but which may imitate the call of the common guillemot.
