Hormiguero Dorsiescamado

<em>Willisornis poecilinotus</em>, the common scale-backed antbird, is a passerine bird in the family Thamnophilidae, order Passeriformes, native to the tropical forests of northwestern South America. Its range encompasses parts of Colombia, Ecuador, and Venezuela, where it inhabits the dense understory of humid lowland and foothill rainforests. This species is typically found foraging close to the forest floor, often following army ant swarms to catch invertebrates flushed by the ants — a foraging strategy known as obligate or facultative ant-following. The common scale-backed antbird is sexually dimorphic; males display distinctive scaled patterning on the back while females typically show rufous-brown tones. The IUCN currently classifies <em>Willisornis poecilinotus</em> as Least Concern, reflecting a stable population within its forest habitat. However, continued deforestation in the Chocó and Amazonian foothills regions poses a longer-term concern for this and many forest-dependent species. Biological traits for this species remain poorly documented in the scientific literature, including precise data on average lifespan, body dimensions, weight, and detailed dietary breakdown beyond its general insectivorous habits.

koala

Icónico marsupial del este y sureste de Australia, los koalas pesan hasta 15 kg y pasan hasta 22 horas diarias durmiendo para conservar energía de su dieta de hojas de eucalipto, baja en calorías. Altamente especializados para procesar los compuestos tóxicos del eucalipto que matarían a la mayoría de los demás mamíferos, poseen microbiomas intestinales únicamente adaptados para la desintoxicación. Clasificado como En Peligro en 2022, con poblaciones diezmadas por la enfermedad de clamidia, la deforestación y el cambio climático.
