Kleine Senckenberg-Reihe 48: Stuttgart. 730924 1 730924 2391929 false 1 In keeping with its strange appearance, the Patagonian mara displays behavioural traits that are very unusual among the rodents. Active during the day, this species spends long periods basking in the sun, either resting on its haunches or with its front limbs folded under its body like a cat. It remains vigilant for predators, however, and when threatened, may escape by galloping or stotting, a high-speed form of locomotion involving rapid bounces using all four limbs at once. Surprisingly, this diminutive species can reach speeds of 45 kilometres per hour over distances in excess of one kilometre. The Patagonian mara consumes a variety of vegetation, usually feeding in grass or shrubland during the day and sheltering in an abandoned burrow of another species, or amongst dense vegetation at night (2).</p><p>Perhaps the most unusual feature of this species is its social and reproductive behaviour. Patagonian maras are strictly monogamous (a rare trait in mammals), forming lifelong pairs that generally avoid contact with conspecifics, except during the curious arrangements that form in the austral summer breeding season. The female Patagonian maras dig burrows, in which the young are often reared communally (2) (3). After a gestation period of 90 days (3), the female gives birth to a litter, usually of two young, close to the entrance of a burrow (1) (2). The young, which are born well-developed, with eyes already open, quickly move into the burrow, which may be co-habited by the offspring of several other breeding pairs (2). The young remain in the vicinity of the burrow for the next four months, where they are visited daily by the mother to be suckled. When the breeding pair visits the burrow, the female makes a shrill call, which brings all the infant Patagonian maras in the burrow to the surface. The female then attempts to discern its own offspring within the group by smell, while chasing off the young of other pairs, which try to, and occasionally succeed, in obtaining the female's milk. Once identified, the female leads its offspring a short distance away from the burrow to be fed, while the adult male keeps watch, chasing off other pairs that approach. The other breeding pairs must therefore wait until the preceding pair have departed, before visiting the burrow. This communal behaviour is thought to help reduce predation, as it means that adults are more frequently present around the burrow (3). b28b406a6d70edadb7c063bb2c5b1578 2606574 Wildscreen Copyright Wildscreen 2003-2008 ARKive Copyright Copyright Wildscreen 2003-2008.
