Patagonian Mara

Fascinating facts about the Patagonian Mara

• Patagonian maras monogamous for life — a rarity among rodents that weigh as much as a rabbit but stand as tall as a hare on their hind legs. A male and female pair will occupy the same burrow for years, sometimes decades, and defend their territory together against rivals. Scientists studying wild populations in Argentina have documented pairs staying bonded across multiple breeding seasons, a social structure virtually unknown in most other rodent species where males abandon females after mating.
• They give birth to fully furred, eyes-open young after just 77 days of pregnancy — one of the shortest gestation periods in any mammal their size. By comparison, a human pregnancy lasts 280 days; a Patagonian mara calf can hop and graze within hours of birth. This ultra-fast development is an evolutionary answer to life on the open steppe, where exposed babies need mobility to survive.
• A Patagonian mara can reach speeds of 45 km/h across the Patagonian desert, jumping up to 2 metres in a single bound — a strategy called 'stotting' where they leap stiffly on all four legs to spot predators like pumas and caracaras over the low scrub. The bouncing motion burns energy but buys the seconds needed to detect danger across flat, treeless terrain where there's nowhere to hide.
• They live in colonies of up to 80 individuals that share burrow systems but forage in monogamous pairs — a social arrangement biologists call 'aggregated polygamy' found nowhere else among rodents. Each mated pair stakes out a feeding territory within the larger warren, allowing them to raise young close to safety while maintaining the bachelor and bachelorette social structure of the wider group.
• Habitat loss and introduced foxes have cut wild Patagonian mara populations by roughly 75% since the 1970s, yet they remain almost entirely absent from zoos outside South America — a conservation blindspot that means fewer eyes on their decline and little captive insurance against extinction. Argentina's remote steppe has become their last refuge, and their near-threatened status reflects a species quietly disappearing from most of its historical range.

About the Patagonian Mara

In the sun-baked steppes of Patagonia, the Mara roams with an air of quiet confidence, its long legs carrying it across the open grasslands with a loping gait that eats up the distance. As it moves, its large ears twitch and swivel, drinking in the sounds of its surroundings, while its sharp eyes scan the horizon for signs of danger, ever vigilant in this land of predators and prey. With its striking coat and powerful build, the Mara is a testament to the enduring spirit of this unforgiving yet beautiful landscape, where only the most resilient creatures can thrive.
