Common Jelly Spot

<em>Dacrymyces stillatus</em>, commonly known as the common jelly spot, is a saprotrophic fungus in the family Dacrymycetaceae. It is classified as Least Concern on the IUCN Red List, with records from five European countries and North America. The species typically grows on damp, dead, or decaying wood, particularly coniferous timber, forming small, gelatinous, orange-yellow cushions or pustules on the substrate surface. As a saprotrophic wood-decay fungus, it contributes to nutrient cycling and the decomposition of woody material in temperate forest ecosystems. The bright gelatinous fruiting bodies make it a conspicuous species when encountered on wet wood in cool, humid conditions. Diet information for this species is not available in current records. 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.
