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.

Common Elephant Tusk

<em>Antalis entalis</em>, the common elephant tusk, is a marine mollusc in the class Scaphopoda, family Dentaliidae, classified as Least Concern by the IUCN Red List. The species is native to European waters and has been documented in Denmark, Norway, and Sweden, inhabiting subtidal and deep benthic zones of the northeastern Atlantic Ocean and North Sea. As a scaphopod, <em>Antalis entalis</em> is characterized by its distinctive curved, tusk-shaped shell that is open at both ends, allowing the animal to partially burrow vertically into sandy or muddy substrates with only the narrow posterior end projecting into the water column. The species feeds on foraminifera and other microscopic organisms in the sediment, capturing prey with specialized tentacle-like structures called captacula that extend through the broader anterior opening of the shell. Scaphopods have limited locomotion and typically remain partially buried throughout their lives. <em>Antalis entalis</em> plays a role in benthic communities as both a consumer of meiofauna and a prey item for predatory fish and invertebrates. Historically, elephant tusk shells of related species were used as currency and ornament by Indigenous peoples of the Pacific Northwest coast. Biological traits of this species remain poorly documented in the scientific literature.
