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.

Trichormus variabilis is a filamentous, nitrogen-fixing cyanobacterium in the family Nostocaceae. It forms heterocysts — specialized nitrogen-fixing cells — within its trichomes and is found in freshwater, soil, and symbiotic associations. Its conservation status is not evaluated.
