Kaldjirkang (Noongar LOTE and Djiraly) or Kaldjerkang (Kongal-marawar), Crested Tern and its scientific name is Thalasseus bergii. Kaldjirkang maambakoort-ngat (birds we often see at the sea shore).
Kaldjirkang feeds mostly at wardan by plunge diving to a depth of up to keny meter, or by dipping from the surface, and food is usually swallowed in mid-air. Birds may forage up to mara mara kilometers from boodjar 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.
There are no global conservation concerns for this bird, which has a stable total population of more than 500,000 individuals.
