Águila cabeza blanca

El ave nacional de los Estados Unidos y símbolo del éxito conservacionista americano, el águila cabeza blanca tiene una envergadura de hasta 2,4 metros y habita bosques y humedales próximos a aguas abiertas en toda Norteamérica. Casi extinta en la década de 1960 por el envenenamiento con DDT y la caza, se recuperó de forma notable gracias a las prohibiciones de pesticidas y la Ley de Especies en Peligro.

Common Brassy Ringlet

The common brassy ringlet (<em>Erebia cassioides</em>) is a butterfly species endemic to high-altitude mountain environments of central and southern Europe, with documented occurrences in Austria, Bosnia and Herzegovina, Bulgaria, and Italy. This species typically inhabits all terrestrial and freshwater environments within its alpine range, favoring subalpine and alpine grasslands at elevations often exceeding 1,500 meters. It is classified as Least Concern on the IUCN Red List, reflecting a currently stable population status. As a member of the family Nymphalidae, the common brassy ringlet often feeds on grasses and sedges during its larval stage, while adult butterflies are typically found nectaring on alpine flowers. The species is often associated with calcareous grasslands and rocky slopes, where it can be seen flying in warm, sunny conditions during the summer months. Biological traits of this species remain poorly documented in the scientific literature.
