Viudita Chaqueña

The cinereous tyrant (Knipolegus striaticeps) is a small flycatcher in the family Tyrannidae, found in the dry, open country of central South America, primarily in Bolivia and northwestern Argentina. It inhabits open woodland, dry scrub, chaco, and woodland edge in arid and semi-arid environments at low to moderate elevations, including the dry valleys of the eastern Andes foothills and the Gran Chaco plains. The male is largely dark gray with streaked underparts, while females are browner with more distinct streaking. The species forages from low perches, hawking insects in short sallies. The cinereous tyrant is classified as Least Concern by the IUCN, with a stable though geographically limited range within the interior of South America. The genus Knipolegus comprises several species of dark tyrant-flycatchers associated with dry, open habitats across South America. Threats to this species include conversion of native dry woodland and chaco to agricultural land, which has been particularly rapid in the lowlands of eastern Bolivia and northwestern Argentina. The species is entirely absent from Europe; any record listing Norway is a database error. Its restricted range within the dry interior of South America means that habitat conservation in Bolivia and Argentina is critical for the species' long-term persistence.

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.
