Sterna albifrons

.

Closely related to S. saundersi, S. antillarum, S. superciliaris and S. lorata (and possibly also S. balaenarum). Some works treat S. antillarum, and sometimes S. saundersi, as conspecific with present species. Apparent hybridization with S. nereis in S Australia indicates possible close relationship; long-term study of relationships required. Form sinensis sometimes treated as a separate species (with pusilla either synonymized with it or included as a race). Race innominata subsumed within nominate. Validity of placens questionable and has been regarded as a synonym of sinensis. Five subspecies recognized.

Subspecies and Distribution
  • S. a. albifrons (Pallas, 1764) – Europe through W Asia E to (at least) Afghanistan#R, also Atlantic coastal Morocco, the Mediterranean coast of N Africa and islands in Persian Gulf; winters on coasts from Africa E to W India.
  • S. a. guineae (Bannerman, 1931) – Ghana to Gabon and along R Niger and major tributaries, with marginal population in Mauritania and Senegal.
  • S. a. pusilla (Temminck, 1839) – N India and Myanmar, and islands off Sumatra and Java.
  • S. a. sinensis (J. F. Gmelin, 1789) – Sri Lanka; SE Russia, China, Japan, SE Asia and Philippines to N Australia; recent colonist from Micronesia (Saipan)#R E to Hawaii most likely this race#R,#R, and also some birds in New Britain and Solomons (Bougainville and perhaps Santa Isabel); N populations winter mostly in Malaysia.
  • S. a. placens Gould, 1871 – E Australia and E Tasmania; some dispersal N to N Australia, possibly also to as far as Indonesia and SW Pacific.
