Common Foxglove

<em>Digitalis purpurea</em> is a biennial or short-lived perennial plant in the family Plantaginaceae, order Lamiales, commonly known as common foxglove. This species is widely cultivated as an ornamental plant and has been naturalized broadly across the globe, with presence documented across Africa, Asia, Europe, North America, Oceania, and South America. <em>Digitalis purpurea</em> typically grows in open woodlands, woodland clearings, hillsides, and disturbed ground, particularly on acidic, well-drained soils. In its first year, the plant forms a rosette of large, softly hairy leaves; in its second year it produces a tall flower spike, often exceeding one meter, bearing distinctive tubular, purple-pink flowers with spotted throats. The flowers are adapted for pollination by bumblebees. The plant contains potent cardiac glycosides, particularly digitoxin and digoxin, compounds that have been critically important in the development of heart failure medications. Despite its medicinal importance, the plant is toxic if ingested. Biological traits of this species remain poorly documented in the scientific literature.

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.
