Collared Palm-Thrush

The Collared Palm Thrush, known scientifically as <em>Cichladusa arquata</em>, is a passerine bird belonging to the family Muscicapidae, the Old World flycatchers. <em>Cichladusa arquata</em> is a notable singer, often characterised by its melodic and varied song delivered from prominent perches. The species typically inhabits woodland, thicket, and savanna habitats, often in areas with scattered trees or dense shrubbery, including areas near human habitation. As the common name suggests, the species is often associated with palm groves and similar vegetation types. It is reported to occur in Norway according to available range data. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Palm Thrush is currently assessed as Least Concern on the IUCN Red List, reflecting a stable global population without significant conservation concerns.

Colombian Small-eared Shrew

<em>Cryptotis colombiana</em>, the Colombian small-eared shrew, is a diminutive insectivorous mammal belonging to the family Soricidae, endemic to Colombia. This species typically inhabits montane environments, including humid cloud forests and high-altitude grasslands known locally as páramo, where it forages actively through leaf litter and soil for invertebrate prey. Small-eared shrews of the genus <em>Cryptotis</em> are characterised by their notably reduced external ears, high metabolic rates, and nearly constant activity cycles driven by the energetic demands of maintaining body temperature. <em>Cryptotis colombiana</em> is currently assessed as Least Concern by the IUCN, suggesting that its population is relatively stable within its Colombian range. Despite this status, Andean shrews face ongoing pressures from land conversion, cattle grazing in páramo ecosystems, and climate-driven shifts in vegetation zones. The species contributes to soil aeration and invertebrate population regulation within its montane habitat. Biological traits of this species remain poorly documented in the scientific literature.
