Andean White-eared Opossum

The Andean White-eared Opossum (Didelphis pernigra) is a species in the genus Didelphis. It is currently classified as Least Concern on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

Common Tailorbird

<em>Orthotomus sutorius</em>, the common tailorbird, is a small passerine in the family Cisticolidae, widely distributed across South and Southeast Asia. Despite one distribution record indicating Norway, the species is primarily a tropical and subtropical resident, inhabiting gardens, scrub, forest edges, and cultivated areas from India through Southeast Asia. It is classified as Least Concern on the IUCN Red List owing to its broad range and adaptability to human-altered landscapes. The common tailorbird is renowned for its remarkable nest construction: the female stitches large leaves together with plant fiber or spider silk to form a cradle in which the cup nest is built, giving the species its common name. It feeds primarily on insects and spiders gleaned from foliage and bark. The song is a loud, repetitive call frequently heard in gardens. Plumage is typically olive-green above with a rufous crown and pale underparts. Biological traits such as precise body weight, wingspan, and lifespan data remain poorly documented in comprehensive standardized assessments, though adults typically weigh between 6 and 10 grams.
