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 Rowan Pigmy

<em>Stigmella nylandriella</em>, the common rowan pygmy, is a small moth in the family Nepticulidae, a group known as pygmy moths or nepticulid moths. The species is distributed across northern and central Europe, with confirmed records from Belgium, Denmark, Norway, and Sweden. As the common name suggests, the larvae of this species are leaf miners of rowan (<em>Sorbus aucuparia</em>) and related trees in the family Rosaceae. The larvae typically create distinctive winding mines in the leaves of their host plants during the growing season, feeding on leaf tissue while sheltered within the mine. Adults are tiny, with wingspans typically just a few millimeters, characteristic of the Nepticulidae family. The species completes its lifecycle through egg, larval, pupal, and adult stages, with adults typically emerging in summer months. It is assessed as Least Concern by the IUCN, reflecting stable populations associated with the widespread availability of rowan trees throughout temperate European forests and hedgerows. The species typically inhabits woodland edges, hedgerows, parks, and gardens where host trees are present. Biological traits such as average lifespan, body measurements, and detailed dietary composition beyond leaf mining behavior remain poorly documented in standardized ecological literature.
