Polluella Pizarra

<em>Neocrex colombiana</em>, commonly known as the Colombian Crake, is a bird species belonging to the genus <em>Neocrex</em> within the family Rallidae, a group of typically secretive marsh and wetland birds. This species is classified as Data Deficient, indicating that current information is insufficient to accurately determine its conservation status, and that further survey work is required to understand its population size and trend. It has been documented in Colombia and Ecuador, where it inhabits various environmental settings consistent with rallid ecology, including wetlands, marshy grasslands, and dense vegetation near water. Rails and crakes in this family are generally omnivorous, feeding on invertebrates, seeds, and small vertebrates, though specific dietary records for this species have not been documented. Biological traits of this species remain poorly documented in the scientific literature. The secretive nature of rallid birds, combined with their preference for dense habitats, makes population surveys challenging. Comprehensive field surveys using acoustic monitoring are considered essential for improving knowledge of <em>Neocrex colombiana</em>.

Pingüino emperador

El pingüino más grande del mundo, el pingüino emperor puede medir hasta 1,2 metros de altura y pesar 45 kg, habitando el continente antártico en algunas de las condiciones más extremas de la Tierra. Se reproduce en la oscuridad del invierno a temperaturas inferiores a -60°C, con los machos incubando un único huevo sobre sus patas bajo una bolsa de cría durante 65 días mientras las hembras están en el mar. Su comportamiento de apiñarse —haciendo circular a los individuos a través del cálido centro de grupos de miles de ejemplares— es una obra maestra de la supervivencia cooperativa.
