Wild Animals in Taiwan

This field guide lists 94 wild animals whose research-grade iNaturalist sightings are concentrated in Taiwan: 31 birds, 25 amphibians, 16 mammals, 14 reptiles and 1 other group. The most frequently recorded are Common Indian Toad, Malayan Night Heron and Brown Shrike. Every species below has its own page with a photo, its scientific name, its conservation status and where it is most observed.

94 — the species in the Tracks field guide for which Taiwan 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. Between them these 94 species account for 245,388 research-grade observations.

Common Indian Toad (Duttaphrynus melanostictus), with 23,058 research-grade observations on iNaturalist — more than any other species on this page. Next most recorded are Malayan Night Heron and Brown Shrike. "Most recorded" means most often photographed and verified by people, which is a good proxy for what a visitor is likely to actually see.

On the Tracks rarity scale the rarest species on this page is Chinese Pangolin (Epic tier), with 500 recorded sightings. Tracks rarity is based on how often a species is actually encountered rather than on its conservation status, so a rare card is a hard animal to find, not necessarily a threatened one.

This guide lists 16 mammals for Taiwan, most-recorded first: Pallas's Squirrel, Formosan Rock Macaque, Crab-eating Mongoose, Asian House Shrew, Formosan Serow and Chinese Pangolin, plus 10 more on this page.

31 bird species are listed for Taiwan. The most frequently recorded are Malayan Night Heron, Brown Shrike, Crested Serpent Eagle, White-rumped Shama, Swinhoe’s White-eye and Pacific Swallow, plus 25 more on this page.

Yes — 14 reptiles and 25 amphibians are listed for Taiwan. They include Taiwan Japalure, Chinese Green Tree Viper, Chinese Stripe-necked Turtle, Indian Forest Skink, Taiwanese Habu and Many-banded Krait, plus 33 more on this page. Reptiles and amphibians are under-recorded almost everywhere relative to birds and mammals, so treat these counts as a floor.

2 of the species on this page belong to the groups behind most wildlife injuries — large carnivores, crocodilians, sharks, venomous snakes and big herbivores. They are Chinese Green Tree Viper and Many-banded Krait. Nearly all of them avoid people given the chance. The practical rules are the same everywhere: never approach, corner or feed a wild animal, keep dogs leashed, store food securely, and give any animal with young a wide berth.

Yes. 2 of the snakes listed for Taiwan belong to venomous groups: Chinese Green Tree Viper and Many-banded Krait. Snake bites are overwhelmingly a result of handling or trying to kill the animal. Treat every snake you can't identify as venomous, back away, and let it leave.

1 marine or coastal species is listed for Taiwan: Crab-eating Mongoose.

10 of the species on this page are IUCN-listed as Vulnerable or worse: Chinese Stripe-necked Turtle (Critically Endangered), Chinese Pangolin (Critically Endangered), Farmland Green Flying Frog (Endangered), Black-faced Spoonbill (Vulnerable), Many-banded Krait (Vulnerable) and Styan's Bulbul (Vulnerable), plus 4 more. Conservation status is shown on every species page.

No insects or arachnids appear on this page — the guide's Taiwan list is mostly birds and amphibians. A species is shown on the page of whichever country records it most, so any insects or arachnids recorded in Taiwan either sit on another country's page or fall outside the guide's 94-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 Taiwan 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 Taiwan, 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.
