brown bear

The world's most widely distributed bear species, brown bears range from North America and Europe across Russia to Japan, occupying forests, tundra, and alpine meadows. Adults can weigh up to 700 kg in coastal Alaskan populations. Omnivores that consume berries, roots, fish, and carrion, brown bears are a keystone species that distribute nutrients across landscapes. Most populations are stable, though some subspecies are threatened.

Long-tailed Sylph

One of the most strikingly ornamented hummingbirds, male long-tailed sylphs have iridescent green plumage and dramatically elongated, ribbon-like outer tail feathers reaching up to 22 cm — over three times the body length. Found in Andean cloud forests of Colombia and Venezuela, they inhabit humid montane forest between 1,400–2,800 meters elevation. Males perform elaborate display flights to attract females. Their extravagant tails are a classic example of sexual selection via female preference.
