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.
cockscomb sainfoin
Cockscomb sainfoin (Onobrychis caput-galli) is a slender, annual or biennial legume in the family Fabaceae, native to dry, rocky grasslands, field margins, and garrigue scrub of western Europe, primarily in Belgium, France, the Netherlands, and the United Kingdom, extending into the Mediterranean basin. Growing to 20–50 centimetres, the plant has pinnately compound leaves and produces loose racemes of small pink to mauve pea flowers in late spring and early summer. The distinctive winged, helmet-shaped pods — resembling a cock's head or comb — give the species both its common and scientific names (caput-galli meaning cock's head in Latin). Unlike the closely related common sainfoin (Onobrychis viciifolia), this species does not spread by creeping rhizomes and is less commonly used in agriculture, though it grows in similar calcareous, well-drained soil conditions. The plant is associated with dry chalk and limestone grasslands, a habitat under significant pressure from agricultural intensification, scrub encroachment, and development across much of its European range. Pollination is primarily by bees attracted to the nectar-rich flowers. Onobrychis caput-galli is Not Evaluated on the IUCN Red List at global scale, though it may be considered locally rare or declining in parts of its northwestern European range where appropriate grassland habitats have diminished substantially over the past century.
