Panthera onca
Tracks along the beach at Corcovado; the animal itself is a gift.
The Americas' great cat carries the strongest bite of any big cat, strong enough to open turtle shells and caiman skulls, which is exactly how it uses it. Jaguars are stockier than leopards, rosettes dotted with central spots, and they treat rivers as roads: few cats swim as readily or as well. Most of the world's jaguars, likely tens of thousands, live in Amazonia; Costa Rica's population is far smaller, threaded through corridors between parks, with Corcovado and the Talamanca ranges as strongholds. Seeing one here is a lottery win, but finding tracks pressed into a beach where a jaguar patrolled for nesting turtles at dawn is a genuine and regular thrill, and somehow almost as good.
Solitary, wide-ranging, comfortable hunting by day or night. Kills by piercing the skull or nape, a technique unique among big cats.
Over 85 recorded prey species: peccaries, deer, sloths, iguanas, fish, caimans, and sea-turtles taken on nesting beaches.
Play the long game: camera traps on permitted trails, or dawn beach walks in turtle season looking for fresh tracks to photograph. In-person sightings are luck; be ready anyway.
Report any jaguar sighting to park staff rather than social media; location leaks are a poaching and disturbance risk. WorldWildMap keeps jaguar records generalised to 25 km.
Generalised encounter areas, not exact locations. Each shape is a grid cell coloured by how likely the species is there.

Tapirus bairdii
Ancient forest engineer; patience is the only technique.

Panthera pardus
Cryptic, solitary, and everywhere, if you know where to look.

Alouatta palliata
The sound of the neotropics at first light.

Bradypus variegatus
Slow-motion cecropia specialists: look up, then look up again.
