Blue Featherleg

A medium-sized damselfly of still and slow-flowing freshwater habitats across Europe and western Asia, blue featherlegs are named for the striking feathery tibia fringe on the males' hind legs, waved during courtship displays. Males display pale blue coloration while females are olive-green. They perch on emergent vegetation and are a good indicator species for water quality in riverine habitats. Populations have declined locally due to water pollution and agricultural intensification.

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.
