The jacanas are a group of wetland birds, which are identifiable by their huge feet and claws, which enable them to walk on floating vegetation in the shallow lakes that are their preferred habitat. In Jamaica, this bird is also known as the 'Jesus bird', as it appears to walk on water.

Linnaeus based his account on the "spur-winged water hen" that had been described and illustrated in 1743 by the English naturalist George Edwards in his A Natural History of Uncommon Birds.

Rare
Under 5% of wildlife watchers report a Northern Jacana sighting in Las Baulas Marine National Park on a given day, based on 56 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 102nd most-seen of the 206 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Northern Jacana in Las Baulas Marine National Park on a given day, against under 5% in February, April–May and October–December, the lowest months. That is one of Las Baulas Marine National Park's wettest months, with about 340 mm of rain against almost none in February.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Northern 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.
23rd of 32
Of the 32 parks where we can rate Northern Jacana sightings, Las Baulas Marine National Park ranks 23rd at under 5%. The best odds are in Palo Verde National Park (Costa Rica, about 70%), Tortuguero National Park (Costa Rica, about 60%) and Lago de Yojoa (Honduras, about 50%). All parks ranked.
Same order: Charadriiformes
The closest relatives of the Northern Jacana that you can see in Las Baulas Marine National Park (order Charadriiformes, Shorebirds and Allies) are Spotted Sandpiper (about 40%), Hudsonian Whimbrel (about 30%) and Royal Tern (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Northern Jacana is recorded against all the birds logged in Las Baulas Marine National Park (56 verified sightings from 2019 to 2026), 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.
