Little Tern (Sternula albifrons)


Taxonomy

Sterna albifrons

Pallas

.

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). Validity of forms innominata and placens questionable; former often included within nominate, and placens has been regarded as a synonym of sinensis. Six subspecies recognized.

Subspecies and Distribution
  • S. a. albifrons (Pallas, 1764) – Europe through W Asia E to (at least) Afghanistan#R, also Atlantic coastal Morocco and the Mediterranean coast of N Africa; winters on coasts from Africa E to W India.
  • S. a. innominata (Zarudny & Loudon, 1902) – islands in Persian Gulf.
  • 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.
