The green ibis (Mesembrinibis cayennensis), also known as the Cayenne ibis, is a wading bird in the ibis family Threskiornithidae. It is the only member of the genus Mesembrinibis. This is a resident breeder from Honduras through Nicaragua, Costa Rica and western Panama, and South America to northern Argentina. It undertakes some local seasonal movements in the dry season.
The green ibis was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it in the genus Tantalus and coined the binomial name Tantalus cayennensis. Gmelin based his description on the "Cayenne ibis" that had been described in 1785 by the English ornithologist John Latham in his book A General Synopsis of Birds. Latham had based his own description on the "Le Courlis des Bois " and the "Courly vert, de Cayenne" that the French polymath, the Comte de Buffon had included in his Histoire Naturelle des Oiseaux. The green ibis is now the only species placed in the genus Mesembrinibis that was introduced in 1930 by James Lee Peters. The genus name Mesembrinibis is a combination of the Greek word mesēmbrinos... Wikipedia →

Possible
About 20% of wildlife watchers report a Green Ibis sighting in Emas National Park on a given day, based on 47 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 86th most-seen of the 187 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
October
In that month about 40% of wildlife watchers report a Green Ibis in Emas National Park on a given day, against about 10% in May–August and November, the lowest months. April and December–February have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Green Ibis sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 33
Of the 33 parks where we can rate Green Ibis sightings, Emas National Park ranks 5th at about 20%. The best odds are in Tortuguero National Park (Costa Rica, about 40%), Anavilhanas National Park (Brazil, about 40%) and Bastimentos Island National Marine Park (Panama, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Green Ibis is recorded against all the birds logged in Emas National Park (47 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.
