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.

clifden nonpareil

The Clifden Nonpareil, Catocala fraxini, is one of Europe's largest and most spectacular moths in the family Erebidae, named for the village of Clifden in Ireland where early specimens were recorded, with 'nonpareil' meaning 'without equal' in French. The forewings are subtly beautiful, with complex gray, brown, and black marbling that provides excellent camouflage against bark when at rest. When disturbed, the moth reveals startlingly vivid hindwings marked with broad bands of blue-lilac and black, a classic startle display intended to deter predators. Adults have a wingspan of up to 90 mm. The species is found from western Europe east through central Asia to Japan, inhabiting mature deciduous woodland and riverside forests where aspen (Populus tremula) and poplars (Populus species) grow, as these are the larval food plants. Adults fly in late summer and autumn, visiting blackberry, ivy, and overripe fruit for sugar-rich food. The Clifden Nonpareil was once widespread in Britain but underwent severe decline during the 20th century due to loss of mature poplar woodland and riverside habitat. Conservation efforts including habitat restoration have allowed gradual recolonization of former British sites. The species is now slowly recovering in parts of southern England.
