Pomarine jaeger (Stercorarius pomarinus)

The pomarine jaeger (Stercorarius pomarinus), pomarine skua, or pomatorhine skua, is a seabird in the skua family Stercorariidae. 
The bird is a migrant, wintering at sea in the tropical oceans.

Charadriiformes, from Charadrius, the type genus of family Charadriidae) is a diverse order of small to medium-large birds. 
Most members of this order can also collectively be referred to as shorebirds.

The English word "skua" comes from the Faroese name for the great skua, skúgvur [ˈskɪkvʊɹ].
The word "jaeger" or Jäger is German for "hunter".
The genus name Stercorarius (and the family name Stercorariidae) is Latin and means "of dung"; the food, once thought to be excrement, disgorged by other birds when pursued by skuas.

The specific Pomatorhinus is from Ancient Greek poma, pomatos, "lid" and rhis, rhinos, "nostrils". The species name  refers to the cere (bill or beak), which the pomarine jaeger shares with the other skuas.
