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.

Luteimonas composti is a gram-negative, aerobic bacterium in the family Xanthomonadaceae, isolated from compost environments where organic matter is undergoing active decomposition. It produces yellow-pigmented colonies and contributes to the biodegradation of organic substrates. Its conservation status is not evaluated.
