Leopard

Highly adaptable big cat with the widest geographic range of any felid, found across Africa, the Middle East, and South Asia in habitats from rainforest to desert. Solitary and largely nocturnal, leopards are powerful climbers that cache prey in trees. Melanistic individuals — black panthers — are common in dense forest populations. Listed as Vulnerable globally.

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.
