A pocket field guide to the world’s wildlife
Most travel writing tells you a place has abundant wildlife and leaves it there. Wildseer tells you which animal, which valley or reef, which month, and how likely you actually are to see it. Every entry is a real record checked against a database rather than a memory, with an honest likelihood attached, and where a species is probably already gone we say so rather than quietly dropping it.
It is written for the traveller who books the dawn boat rather than the lie-in. Not an expert, but not satisfied with monkeys and elephants either.
Nothing here is sponsored. No operator can buy a place on this site and none ever will.
Two countries so far: Thailand and Sri Lanka
Thailand came first and is covered in full: 517 species across every group, from the Indochinese tiger down to the leeches, tied to fifteen specific places. Sri Lanka followed, with 397 species across twenty-eight places, including the densest leopard population recorded anywhere and the largest gathering of wild elephants in Asia. Between them that is 684 species and 2,873 individual records.

Going somewhere specific?
Park and island guides list what is genuinely present at that one place, not what is present in the country.
Places
Going in a particular month?
Seasons matter more than most guides admit. On the Andaman coast the diving season and the monsoon are opposites. In the forest, the dry months concentrate mammals at water while the green months belong to frogs and insects. These pages are built from the same records, filtered to what is actually around.
- Thailand in December, the dry season at its best
- Thailand in July, the green season and what it gives you
- Similan Islands in February, peak diving
- Khao Yai in August, waterfalls in full flow
How this is put together
Every species sits in a structured record: where to look, which months, and an honest likelihood running from Common down to Ultra rare. Ultra rare means a once-in-a-lifetime record, not a famous animal. Nothing is invented to fill a page, and if a group looks thin it is because the evidence is thin.
The guide also records loss. The largetooth sawfish and the masked finfoot are both listed for Thailand and both are very likely gone. A field guide that quietly drops them tells you the sea is richer than it is.

What is coming
Region by region, with the next country already being scoped. Global species pages, printable checklists, and reverse lookups for the question people actually ask, which is not what lives in Thailand but where in the world can I see a manta ray.
