Broad Bean Rust

The Broad Bean Rust (Uromyces viciae-fabae) is a species in the genus Uromyces. Native to Europe and North America and South America, inhabiting ecosystems characteristic of the region.

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.
