The lesser capybara (Hydrochoerus isthmius) is a large semi-aquatic rodent found in South America that has vast similarities with, yet subtle differences from, the slightly larger common capybara (Hydrochoerus hydrochaeris), the largest species of rodent in the world.
The lesser capybara mainly inhabits areas close to water such as marshes, ponds, and lagoon habitats as these places offer water, which is essential for these capybaras to fulfil their niches' of maintain body temperature homeostasis, provide suitable food, hide from predators, and mate. They were first observed in Pacific river valleys in Panama as early as 1912 as a subspecies of the common capybara. However, after thorough studies on the anatomy and genealogy of them, the lesser capybara was classified as its own species some time in the 1980s. Currently, this species has expanded its range to parts of Eastern Panama and Western Colombia and Venezuela, just west of the Andes Mountains. The lesser capybara constitutes the northernmost population of any extant capybara species, other than the now extinct H. hesperotiganites from Pleistocene California.

With luck
About 10% of wildlife watchers report a Lesser Capybara sighting in Panama City on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 10th most-seen of the 11 mammals we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March–April, August and November–December
In those months about 10% of wildlife watchers report a Lesser Capybara in Panama City on a given day, against under 5% in January–February, May–July and September–October, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Lesser Capybara sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Panama City, in our data
Panama City is the only city on Wallace's Line with enough records to rate Lesser Capybara sightings: about 10% of wildlife watchers there report one on a given day.
Same order: Rodentia

GBIF citizen-science records
It is estimated from how often the Lesser Capybara is recorded against all the mammals logged in Panama City (8 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.
