The lesser grison (Galictis cuja) is a species of mustelid from South America. Lesser grisons have a long, slender body, short legs, and a bushy tail. They have a long neck and a small head with a flattened forehead and rounded ears. They are smaller than the closely related greater grison, with a head-body length of 27 to 52 cm (11 to 20 in) and a tail 14 to 19 cm (5.5 to 7.5 in) long. Adults weigh from 1.2 to 2.4 kg (2.6 to 5.3 lb). Females are slighter smaller and more slender than males.
The top of the head, the back and flanks, and the tail have coarse black guard hairs with buff-coloured tips over a softer undercoat, giving them a grizzled, greyish colour. The remainder of the body is black or nearly so, apart from a pale, buff-coloured stripe running from the forehead to the shoulders along the lower margin of the grey furred area. The feet are webbed, with five toes ending in sharp, curved claws.
Lesser grisons are found throughout most of southern South America from sea level to as high as 4,200 m (13,800 ft) elevation. They are found in a wide range of habitats, although generally near water, including grasslands, forests,... Wikipedia →

Possible
About 20% of wildlife watchers report a Lesser Grison sighting in El Palmar National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 8 mammals 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.
May
In that month about 60% of wildlife watchers report a Lesser Grison in El Palmar National Park on a given day, against under 5% in January–March, June and August–November, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Lesser Grison sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only El Palmar National Park, in our data
El Palmar National Park is the only park on Wallace's Line with enough records to rate Lesser Grison sightings: about 20% of wildlife watchers there report one on a given day.
Same order: Carnivora
The closest relatives of the Lesser Grison that you can see in El Palmar National Park (order Carnivora, Carnivorans) are Crab-eating Fox (about 70%) and Pampas Fox (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lesser Grison is recorded against all the mammals logged in El Palmar National Park (8 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.
