The bird has olive-green plumage with two white wing bars and a white eye-ring. Males have a red crown patch, which is usually concealed. The sexes are identical (apart from the crown), and juveniles are similar in plumage to adults. It is one of the smallest songbirds in North America. The ruby-crowned kinglet...

Wildlife Atlas — real photographs

🦁 All species

Animals chosen by hand, plus every species the world photographs most — each with real research-grade photographs from the iNaturalist community.

🔤 Every species, A–Z

The full atlas in one page: 403 species in alphabetical order.

🦋 Monarch Butterfly

Famous for a two-to-three-generation migration across a continent each autumn — no individual makes the round trip, yet the map is inherited. Milkweed is the only nursery its caterpillars accept.

🐅 Bengal Tiger

The most numerous tiger subspecies, mostly inside India’s reserves. Fewer than 4,000 remain wild — an increase from the ~1,600 lows of the 1970s, proof that protection works when funded.

🐆 Snow Leopard

High-central-Asia ghost: fur the colour of scree, a tail nearly body-length for balance on cliffs. Counted from camera traps and scat DNA because almost nobody has ever seen one at close range.

🐼 Giant Panda

A carnivore’s gut on a bamboo diet — it must eat 10+ hours daily. Downgraded from Endangered to Vulnerable in 2016 after reserve expansion grew wild numbers by roughly 17% in a decade.

🐘 African Savanna Elephant

The largest land animal: up to 6 tonnes, ears that work as radiators, and a matriarchal memory for water across decades. A keystone engineer — whole landscapes depend on their browsing.

🦊 Red Fox

The widest-ranging land carnivore on Earth — native across the northern hemisphere and introduced (and damaging) in Australia. Hunts rodents by hearing, pouncing ear-down into snow.
