THE SOUTHERN BROWN-WINGED TERN,
Sterna antarctica Lesson, Traite d'Orn., p. 621 (1831) (Isle de Prance). Sterna anaestheta. Blanf. & Oates, iv. p. 323 (part.).
Vernacular names. None recorded.
Description. Similar to the preceding race but the white on the primaries is more extensive and more conspicuously pure white, whilst the white on the tail-feathers is less in extent and more sullied with brown.
Colours of soft parts as in the other races.
Measurements. Wing 218 to 239 mm.; culmen 29 to 36 mm.
Birds in Winter plumage and young differ in the same way as those of the preceding race.
Distribution. Seychelles, Mauritius, Laccadives, Maldives, Ceylon and the coasts of Malabar.
Nidification. Similar to that of the two preceding species. The eggs cannot be distinguished from theirs and vary in the same way. One is the normal clutch, two being very exceptional. This race breeds within our limits on the Vingorla Bocks in great numbers during the Bains, probably June and July. Hume found on these rocks the remains of many birds and eggs but no one since has visited this place at the proper season, so their breeding has never yet been witnessed. Hume's eggs averaged about 43.2 x 30.1 mm. This Tern also probably breeds both on the Maldives and Laccadives.
Habits. Those of the species.
