Cocoa Thrush

The cocoa thrush (Turdus fumigatus) is a medium-sized thrush in the family Turdidae, native to the tropical forests, gardens, and woodland edges of the Lesser Antilles and northern South America, including Trinidad, Tobago, Venezuela, Guyana, Suriname, French Guiana, and northern Brazil. Like other Turdus thrushes, it is primarily a ground and low vegetation forager, consuming earthworms, insects, berries, and small fruits; its melodious, flute-like song is a characteristic sound of its forest and garden habitats. The species is named for its plain, smoky-brown plumage — fumigatus meaning smoke-coloured in Latin — with little differentiation between sexes. It inhabits primary and secondary forest, cocoa and citrus plantations, and shaded gardens, showing tolerance for modified land use that has allowed it to persist in many humanised landscapes. Nesting occurs in trees or shrubs; clutches are typically two to three eggs, incubated by the female alone. The cocoa thrush has no natural presence in Norway; country-level database records to that effect are artefacts. It is classified as Least Concern by the IUCN, with wide distribution and stable or increasing populations in some areas due to its adaptability to modified habitats. It is closely related to the similar cocoa thrush assemblage of Turdus thrushes found across the Neotropics, and taxonomy within the group has been subject to ongoing revision.

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.
