The Bagnas nature reserve is home to a rich biodiversity, and although birds are the stars of this ecosystem (migratory birds, pink flamingos, etc.), it is also a refuge for exceptional fauna, especially mammals.
More specifically, here are some nocturnal mammals you might encounter in the reserve, at dusk or during the night, as well as tips on how to observe them.
Nocturnal mammals of Bagnas
1. Red fox (Vulpes vulpes)
The red fox is a discreet and adaptable carnivore that can be found in the Bagnas reserve. Mainly active at night, it feeds on small mammals, birds, insects and sometimes fruit. It is renowned for its ability to adapt to different environments, even wetlands like those of the Bagnas.
2. Bats
The wetlands of the Bagnas, as well as the surrounding woods and meadows, are favorable habitats for several species of bats, which play a key role in controlling insect populations.
Different species can be observed, such as :
– the Common Pipistrelle (Pipistrellus pipistrellus), often visible at dusk, flying over the surface of ponds to hunt mosquitoes and other insects;
– the Common Serotine (Eptesicus serotinus), larger than the Pipistrelle, prefers to hunt over meadows and clearings for large insects such as beetles;
– the Scarlet-eared Sparrow (Myotis emarginatus), a rarer species, which also feeds on insects in wetlands and meadows.
3. The European hedgehog (Erinaceus europaeus)
Often associated with gardens, the European hedgehog is also present in natural environments such as Bagnas.
It’s a nocturnal, omnivorous mammal that feeds on insects, slugs, small mammals and sometimes fruit.
It can be seen in wooded areas or near hedges and bushes bordering the reserve.
4. The European badger (Meles meles)
Badgers are another nocturnal mammal to be found in the Bagnas region.
It is particularly active at dusk and night, foraging for food in the soil (earthworms, insects, berries and fruit).
This animal is generally difficult to observe, but signs of its presence, such as burrows or tracks, can be spotted.
5. European hare (Lepus europaeus)
Although active throughout the day, hares are particularly active at dusk and during the early hours of the night.
It can be found in the meadows and fields around the reserve, feeding on grasses, plants and young shoots.
6. Wild boar (Sus scrofa)
The wild boar is another nocturnal mammal that can be found in the Bagnas reserve, although it is generally more present in the surrounding forests.
It comes out at night to feed on roots, tubers, small animals and fruit.
Its presence is discreet, but traces left on the ground, such as footprints or signs of excavation, can reveal its passage.
7. Coypu (Myocastor coypus)
Although mainly active during the day, the coypu is a semi-aquatic mammal that can be observed at dusk.
Originally from South America, this herbivore has colonized the wetlands of southern France, and is often seen near the Bagnas ponds, where it feeds on aquatic plants.
8. The European otter (Lutra lutra)
More rare and difficult to observe, the European otter has been sporadically spotted in certain Languedoc wetlands, including the Bagnas.
This nocturnal, semi-aquatic animal is an excellent swimmer and feeds on fish, amphibians and small crustaceans.
The presence of an otter is generally a good indicator of the ecological quality of a wetland.
Tips for observing nocturnal mammals at Bagnas
Don’t hesitate to contact the ADENA* association, which sometimes organizes evening visits and conferences.
Following on from the outing devoted to nocturnal mammals on October 24, ADENA is offering an immersive evening on Friday November 29, with a talk by Samuel Busson. The expert in biodiversity and lighting at CEREMA (Centre d’études et d’expertise sur les risques, l’environnement, la mobilité et l’aménagement) will discuss the impact of light pollution on these animals.
In addition, an exhibition on this subject is freely accessible at the Maison de la Réserve, located at the Domaine du Grand Clavelet, throughout the autumn.

2. Adopt the right gestures
🤫 Be discreet: nocturnal mammals are generally very sensitive to noise and movement. If you hope to observe one of them, it’s important to be quiet and move slowly.
🔦 Use a red lamp: If you’re exploring the reserve at night, a red-light lamp is recommended, as it disturbs the animals less than white light.
🔎 Observe signs of presence: Even if you can’t see the mammals directly, you can spot tracks, droppings, burrows or footprints that testify to their passage.
We wish you good luck! The Bagnas reserve is a magnificent place, rich in nocturnal mammals, for those who know how to observe them calmly, respectfully and patiently.

ADENA (association de défense de l’environnement et de la nature des pays d’Agde) is a non-profit organization created to protect and enhance the natural heritage of the Agde region.
Since it was founded in 1983, it has managed the Bagnas National Nature Reserve, a major site for biodiversity, by carrying out preservation, environmental education and public awareness initiatives.
ADENA is also involved in scientific research and the promotion of local sustainable development, while encouraging cohabitation between man and nature.
