Physical description Click here for a physical description Comb-crested Jacanas are small wetland birds with enormous feet. Their most prominent feature is the orange- to pink-coloured frontal shield. Throat, cheeks and the front of the neck are white, bordered by yellow to orange feathers. The yellow around the eyes is dissected by a black eye stripe. Comb-crested Jacanas have a broad black chest band, while the belly and vent are white again. The upperparts (cap, nape of the neck uppertail) are black, while the upperwings are dark-brown. The bill is yellow with a black tip, legs and feet are greyish olive-green. Their toes are so long that the feet can carry the birds' weight on a floating lily pad. The only difference between the sexes is that males are much smaller than females. Juvenile birds do not have a frontal shield yet and their plumage has less contrast than that of adults. Twitcher's tip When observing birds with one's eyes near water level, i.e. when not seeing the leaves just under the water's surface, one can easily understand how the Comb-crested Jacana came by its nickname as "Jesusbird".

Taxonomy, classification See Comb-crested Jacana at Wikipedia .

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Comb-crested Jacana is available HERE . Comb-crested Jacanas populate some islands in eastern Indonesia, New Guinea and parts of Australia. In Australia, Comb-crested Jacanas, race "novaehollandiae", are only found in the tropical North of the continent, including inland billabongs, and along the East coast and eastern hill ranges of QLD and along a narrow coastal strip of northern NSW. Comb-crested Jacanas live mostly around coastal or near-coastal freshwater, such as e.g. billabongs, lakes or swamps.

Sightings Click here for sighting information Race "novaehollandiae" A Comb-crested Jacana, race "novaehollandiae", was first seen by us on a billabong in the NT in October 1997, walking on lily pads. Comb-crested Jacanas, race "novaehollandiae", were also spotted by us in the wetlands of Capricorn Resort, Yeppoon, in July 2009. Special access to the wetlands kindly granted by the owners of Capricorn Resort is most gratefully acknowledged. C. Hayne reports spotting a Comb-crested Jacana, race "novaehollandiae", in wetlands near Moree, NSW, including Whittaker's Lagoon, all of which are outside the nominal range of the species. B. Hensen reports spotting Comb-crested Jacanas, race "novaehollandiae", at Fogg Dam NR, NT, in August 2013. We spotted them at the same location in August 2014 and M. Eaton found the species there in July 2020. M. Mearns reports spotting Comb-crested Jacanas, race "novaehollandiae", at Gordonbrook Dam, near Kingaroy, QLD, in December 2015. M. Eaton reports finding Comb-crested Jacanas, race "novaehollandiae", regularly in various wetlands in south-eastern QLD. P. Brown found Comb-crested Jacanas, race "novaehollandiae", at McMinns Lagoon, 30 km South of Darwin, NT, in September 2018, and others at the Palmerston Golf Club, Palmerston, NT, in December 2019.

Behaviour

Comb-crested Jacana with two young chicks; note that the colour pigment of the bird's fleshy comb is orange-yellow; the usual pinkish-red comes from circulating blood - when a Comb-crested Jacana becomes excited, blood flow to the crest is restricted and its colour consequently changes from pinkish-red to orange-yellow (photo courtesy of M. Eaton)
