The wattled jacana (Jacana jacana) is a wader in the family Jacanidae found throughout much of South America east of the Andes, as well as western Panama and Trinidad. It is the only species in the Jacanidae family with such a large distribution. Wattled jacanas have long toes and claws which help them walk through aquatic vegetation. Like the majority of species of jacanas, the female is larger than the male, and forms harems of up to 4 or 5 males at any given time. There is also a major difference in proportional development or ornamentation (facial crest and wing size) and defense (length of wing spur) relative to body size when compared to males.
"Jacana" comes from the Tupi word ñaha'nã which means "very loud bird". The wattled jacana lays four black-marked brown eggs in a floating nest. The male, as with other jacanas and some other wader families like the phalaropes, takes responsibility for incubation, with two eggs held between each wing and the breast. The females are polyandrous and will help to defend the nests of up to four mates.
These are conspicuous and unmistakable birds. They are 17–23 cm (6.7–9.1 in) long, but the... Wikipedia →

With luck
About 10% of wildlife watchers report a Wattled Jacana sighting in Rosario on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 84th most-seen of the 121 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May
In that month about 30% of wildlife watchers report a Wattled Jacana in Rosario on a given day, against under 5% in June–August, October and December–February, the lowest months. That is one of Rosario's driest months, with about 50 mm of rain against 150 mm in March.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Wattled 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.
14th of 31
Of the 31 cities where we can rate Wattled Jacana sightings, Rosario ranks 14th at about 10%. The best odds are in Barranquilla (Colombia, about 40%), Santa Cruz de la Sierra (Bolivia, about 40%) and Buenos Aires (Argentina, about 30%).
Same order: Charadriiformes
The closest relatives of the Wattled Jacana that you can see in Rosario (order Charadriiformes, Shorebirds and Allies) are Southern Lapwing (about 60%), Black-necked Stilt (about 20%) and Grey-hooded Gull (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Wattled Jacana is recorded against all the birds logged in Rosario (23 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.
