Which order groups *Xema sabini* with shorebirds, auks, and other gulls and terns?
Answer
Charadriiformes
The scientific classification places *Xema sabini* within the Order Charadriiformes. This order is notable for its evolutionary breadth, encompassing groups that look quite different ecologically, such as classic wading birds like plovers and sandpipers, alongside auks, gulls, and terns. The placement of the Sabine's Gull in this specific order reflects deep, ancestral morphological and genetic connections to the shorebird lineage, even though the adult gull has adapted to a highly pelagic, oceanic existence outside of its breeding season in the High Arctic.
