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.
The northern jacana was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He placed it with the coots in the genus Fulica and coined the binomial name Fulica spinosa. 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.

With luck
About 10% of wildlife watchers report a Northern Jacana sighting in León on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 106th most-seen of the 124 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report a Northern Jacana in León on a given day, against under 5% in January–March, May and July–November, the lowest months. That is one of León's driest months, with about 5 mm of rain against 170 mm in July. June has too few records to rate.
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.
Among the best
Of the 5 cities where we can rate Northern Jacana sightings, León ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in San Pedro Sula (Honduras, about 10%).
Same order: Charadriiformes
The closest relatives of the Northern Jacana that you can see in León (order Charadriiformes, Shorebirds and Allies) are Black-necked Stilt (about 40%), Killdeer (about 40%) and Spotted Sandpiper (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 León (7 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.
