The comb-crested jacana (Irediparra gallinacea), also known as the lotusbird or lilytrotter (though these names are sometimes used to describe Jacanidae as a whole), is the only species of jacana in the genus Irediparra. Like other jacana species, it is adapted to the floating vegetation of tropical freshwater wetlands.
This species is unmistakable. It has a black crown and hindneck with a fleshy red wattle covering the forehead and forecrown, contrasting with a white face and throat. The comb is pinker in breeding adults, more orange when not breeding. There is a broad black band on the lower breast with white belly. The underwing and flight feathers, which show most prominently in flight, are black. Back and upperwing mainly grey-brown with black primary coverts, rump and tail. The long legs with extremely long toes trail in flight. The male is slightly smaller than the female and measures 20–22 cm (7.9–8.7 in) in length and weighs 68–84 g (2.4–3.0 oz). The female measures 24–27 cm (9.4–10.6 in) in length and weighs 120–150 g (4.2–5.3 oz). The wingspan ranges from 39 to 46 cm (15 to 18 in).

Possible
About 20% of wildlife watchers report a Comb-crested Jacana sighting in Brisbane on a given day, based on 2,590 verified sightings from GBIF citizen-science data. It is the 56th most-seen of the 237 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May–September and December–March
In those months about 20% of wildlife watchers report a Comb-crested Jacana in Brisbane on a given day, against about 10% in April and October–November, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Comb-crested Jacana sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Comb-crested Jacana sightings: about 20% of wildlife watchers there report one on a given day.
Same order: Charadriiformes
The closest relatives of the Comb-crested Jacana that you can see in Brisbane (order Charadriiformes, Shorebirds and Allies) are Masked Lapwing (about 50%), White-headed Stilt (about 10%) and Bush Stone-curlew (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Comb-crested Jacana is recorded against all the birds logged in Brisbane (2,590 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
