Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

pigargo-americano

A ave nacional dos Estados Unidos e símbolo do sucesso conservacionista americano, a águia-careca tem uma envergadura de até 2,4 metros e habita florestas e zonas húmidas próximas de águas abertas em toda a América do Norte. Quase extinta na década de 1960 devido ao envenenamento por DDT e à caça, recuperou de forma notável após as proibições de pesticidas e a Lei das Espécies em Perigo.

Cobble Forget-me-not

Cobble forget-me-not (Myosotis schistosa) is a small annual or biennial herb in the family Boraginaceae, native to riverine and coastal habitats in parts of Europe, particularly associated with slate, shale, or schist substrates and disturbed gravelly or rocky ground. Like other Myosotis species, it bears the typical small, five-petalled blue flowers with a yellow eye that give forget-me-nots their widespread recognition. The genus Myosotis encompasses dozens of species distributed across Europe, Asia, North America, and the Southern Hemisphere, many of which are adapted to specific, often nutrient-poor or geologically specialised substrates. Cobble forget-me-not is assessed as Data Deficient by the IUCN, reflecting limited information on its distribution, population size, and ecology. Botanical surveys in appropriate habitats across its inferred range—particularly slate-rich riverbanks and coastal cobble in Europe—are needed to clarify its taxonomy, distribution, and conservation requirements. Like many small annual herbs in disturbed habitats, it may be locally common in suitable microsites but easily overlooked due to its small size and annual habit.
