(2076) Thalasseus bergii bakeri.

THE MEKRAN LARGE CRESTED TERN.

Thalasseus bergi bakeri Mathews, Birds of Australia, ii, p. 346 (Sept. 1912) (Mekran coast). Sterna bergii. Blanf. & Oates, iv, p. 314 (part.).

Vernacular names. None recorded.

Description. Similar to the preceding but breeding birds are darker and they are also slightly larger and have decidedly stouter bills.

Colours of soft parts as in the other races.

Measurements. Wing 833 (exceptional) to 385 mm.; tail 150 to 205 mm.; tarsus 33 to 35 mm.; culmen 61 to 70 mm.

Distribution. Sind, Mekran coast and Persian Gulf.

Nidification. This Crested Tern breeds from May to July on the islands of the Persian Gulf and off the Mekran coast. In some of these islands the colonies number thousands, in others two or three hundred only. Eggs and nests resemble those of the preceding bird. One hundred average 67.5 x 42.5 mm.

There are also breeding-places of this species of Tern off the northern coast of the Bay of Bengal from the Sunderbands to the coast of Akyab, but these all probably belong to the smaller race, edwardsi.

Habits. Similar to those of the preceding race. More material for comparison of the races is badly wanted by the British Museum, especially from the East Indian and Burmese coasts.
