Golden Eagle

Among the most powerful and widely distributed raptors in the world, golden eagles have wingspans reaching 2.2 meters and inhabit mountainous terrain across the Northern Hemisphere. Supreme aerial hunters, they use soaring flight and steep dives at speeds over 200 km/h to capture rabbits, hares, ground squirrels, and occasionally young deer and foxes. In many cultures they have been central to falconry traditions spanning millennia.

Usnea cornuta is a fruticose lichen in the family Parmeliaceae, assessed as Near Threatened (NT). It forms shrubby, branching thalli that hang from tree branches and twigs, typically in humid forest environments. Like all Usnea species, it is highly sensitive to air pollution, particularly sulfur dioxide, making it a useful bioindicator of air quality.
