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.

Foca común

El pinípedo de distribución más amplia, la foca común (Phoca vitulina) habita las costas templadas y subárticas del Atlántico Norte y el Pacífico Norte. Los adultos alcanzan hasta 130 kg y pasan aproximadamente el mismo tiempo en el mar cazando peces, calamares y crustáceos que descansando en playas y rocas. Sus grandes y expresivos ojos están adaptados para la visión subacuática en condiciones de poca luz. La foca común es una fuente de alimento fundamental para orcas, tiburones y osos polares.
