climbing-oleander

Climbing Oleander, Strophanthus gratus, is a woody liana or climbing shrub in the family Apocynaceae native to tropical West and Central Africa, occurring in rainforest margins, gallery forest, and secondary forest from Senegal to Uganda. The species belongs to a genus celebrated for the cardiac glycosides and arrow poisons produced in the seeds; Strophanthus species were the source of the drug ouabain (g-strophanthin), historically used in cardiac medicine and by African hunters as an arrow poison applied to hunting darts. Climbing Oleander produces large, funnel-shaped flowers with white to pale pink twisted petals and a fringe of elongated lobes at the corolla mouth, borne in terminal cymes that are highly ornamental. The name 'climbing oleander' refers to the superficial resemblance of the flowers to the related Mediterranean oleander (Nerium oleander). The species climbs by twining its stems around supporting vegetation and is occasionally cultivated as an ornamental in tropical gardens. The seeds contain strophanthin and other potent glycosides that affect the cardiac system; all parts of the plant are toxic if ingested. The species is not currently assessed as threatened within its native tropical African range.

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.
