Wild Animals in Réunion

This field guide lists 1 wild animal whose research-grade iNaturalist sightings are concentrated in Réunion: 1 mammal. The most frequently recorded is Tail-less Tenrec. Every species below has its own page with a photo, its scientific name, its conservation status and where it is most observed.

Just one — the single species in the Tracks field guide for which Réunion holds the most verified sightings. This is not a complete national checklist: a species recorded even more often in a neighbouring country appears on that country's page instead, and the Tracks app itself catalogues 40,286 species worldwide. That one species carries 259 research-grade observations.

Tail-less Tenrec (Tenrec ecaudatus), with 259 research-grade observations on iNaturalist — more than any other species on this page. "Most recorded" means most often photographed and verified by people, which is a good proxy for what a visitor is likely to actually see.

Only one species is listed for Réunion — Tail-less Tenrec — so it is both the most and the least often recorded animal here, at 259 sightings. Tracks rates it Common tier, a scale based on how often a species is actually encountered rather than on its conservation status.

This guide lists 1 mammal for Réunion, most-recorded first: Tail-less Tenrec.

No birds appear on this page — the guide's Réunion list is a single mammal. A species is shown on the page of whichever country records it most, so any birds recorded in Réunion either sit on another country's page or fall outside the guide's 1-species slice.

No reptiles or amphibians appear on this page — the guide's Réunion list is a single mammal. A species is shown on the page of whichever country records it most, so any reptiles or amphibians recorded in Réunion either sit on another country's page or fall outside the guide's 1-species slice.

The single species listed for Réunion does not belong to the groups usually treated as dangerous to people — bears, big cats, wolves, crocodilians, sharks or venomous snakes. That is a fact about this list rather than a safety guarantee: keep your distance from any wild animal, and check local advice before heading into the backcountry.

No snakes are listed for Réunion. This page is the slice of the guide where Réunion holds the most records, so it under-counts anything recorded more often elsewhere.

No marine or coastal species are listed for Réunion. The single species here is the one most associated with Réunion in the guide, not the country's full fauna.

The single species listed for Réunion does not carry an IUCN Vulnerable, Endangered or Critically Endangered assessment in this dataset. Many species are simply unassessed, and the guide favours species people record often — which skews it toward animals that are doing comparatively well.

No insects or arachnids appear on this page — the guide's Réunion list is a single mammal. A species is shown on the page of whichever country records it most, so any insects or arachnids recorded in Réunion either sit on another country's page or fall outside the guide's 1-species slice.

Dawn and the hour before dusk, almost everywhere and for almost every species: most mammals are crepuscular, and birds are loudest and most active in the first hours of daylight. Weather matters as much as season — overcast, still mornings after rain are productive, and hot midday hours are the worst time to be out looking. Each species page links to its iNaturalist record, where the observation dates show when people in Réunion actually recorded it.

National parks, nature reserves and protected wetlands concentrate both animals and the people recording them, but the edges are often better than the core: hedgerows, riverbanks, coastal paths, and the scrubby margins between habitats. Cities count too — a large share of the sightings behind this page were logged in parks, gardens and suburbs. Because every species here is backed by iNaturalist records, its species page links straight to the map of where it has actually been observed.

Photograph it if you safely can, and note the size, habitat and behaviour. The Tracks app scans the area you're standing in and shows the animals people have actually recorded there, which narrows an identification far faster than searching a national list. If the animal you saw isn't in Tracks yet, add it on iNaturalist: its community will help you put a name to it, and because Tracks is built from iNaturalist's research-grade observations, a sighting verified there feeds back into the data behind pages like this one.

No — and in many places it is also illegal. Feeding is the fastest way to ruin a wild animal. It teaches them to associate people with food, so they lose their wariness and start working car parks, campsites and picnic tables; a habituated animal that begins grabbing food gets labelled a nuisance and is usually destroyed or hit by a road vehicle. Human food is the wrong food too: bread and processed snacks cause malnutrition and wing deformities in birds and gut damage in mammals. And artificial feeding concentrates animals at densities they would never reach naturally, which is how disease spreads through a local population. If you want wildlife closer to you in Réunion, do it by habitat — native planting, a clean water dish, leaving dead wood and leaf litter alone — which supports animals without teaching them to approach people.

No. Keep your distance from every wild animal, however calm it looks — a good rule of thumb is that if the animal changes its behaviour because of you, you are already too close. Don't handle snakes or reptiles, keep dogs leashed near wildlife, and if you find an animal that is injured or appears orphaned, contact a local wildlife rescue or the relevant authority rather than picking it up.
