Wp/nys/Kaldjirkang - Kaldjerkang (Crested Tern)
Kaldjirkang (Noongar LOTE and Djiraly) or Kaldjerkang (Kongal-marawar) is called in English the Crested Tern and its scientific name is Thalasseus bergii. Kaldjirkang maambakoort-ngat (birds we often see at the sea shore).
Kaldjirkang feeds mostly at sea by plunge diving to a depth of up to 1 m, or by dipping from the surface, and food is usually swallowed in mid-air. Birds may forage up to 10 km from land in the breeding season. Kaldjirkang is an adaptable bird that has learned to follow fishing boats for jettisoned bycatch, and to use unusual nest sites such as the roofs of buildings and artificial islands in salt pans and sewage works. Its eggs and young are taken by gulls and ibises, and human activities such as fishing, shooting and egg harvesting have caused local population declines. A study of an area of the Great Barrier Reef where the number of breeding great crested terns has grown ten-fold, probably due to extra food from trawl by-catch, suggested that lesser crested and sooty terns have moved away and now breed on a part of the reef where fishing is banned.
There are no global conservation concerns for this bird, which has a stable total population of more than 500,000 individuals.
