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.

Sphacelaria tribuloides is a small, tufted brown alga forming compact cushion-like colonies on rocky substrates and larger algae. It inhabits intertidal and shallow subtidal rocky zones in temperate and tropical seas worldwide. This photosynthetic alga reproduces via characteristic star-shaped propagules and colonizes rocky marine surfaces.
