Current knowledge of the poorly studied diet of the comb-crested jacana (Irediparra gallinacea)
Tóm tắt
Dietary studies inform species conservation management. The comb-crested jacana (Irediparra gallinacea) is unique amongst avian diversity within its distribution and is listed as threatened under New South Wales legislation in Australia but has been the subject of few biological studies. This short communication summarises present information on dietary items of this species. Plant dietary items are generally known to comprise seeds and vegetable matter, with current information identifying food from 16 species from eight orders and 11 families. Fauna dietary items comprise four classes of invertebrates (Insecta, Arachnida, Malacostraca, Ostracoda) and two classes of vertebrates (Amphibia, Actinopterygii). A reported observation of predation of an Empire Gudgeon (Hypseleotris compressa) is the only fauna dietary item identified to species level to date. There remains much more to learn about the diet of the comb-crested jacana and thus further studies are encouraged.
