large flying fox

The world's largest bat species, large flying foxes have wingspans reaching 1.5 meters and inhabit tropical forests from Southeast Asia to the Philippines and Indonesia. Despite the alarming name, they feed exclusively on fruit and nectar, making them vital pollinators and seed dispersers for tropical forest trees. Roost in massive colonies of thousands. Listed as Vulnerable due to hunting for bushmeat and habitat destruction.

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.
