About These Birds
Greater White-fronted Goose
El ánsar careto o ganso careto mayor es un ganso mediano de color pardo con una llamativa mancha blanca en la frente y barras negras en el vientre. Tiene un amplio rango de cría en la tundra ártica del hemisferio norte y migra a zonas templadas de Europa, Asia y América del Norte para pasar el invierno, donde a menudo se reúne en grandes bandadas en campos agrícolas.
Common Eider
El eider común es el pato más grande de Europa y uno de los más reconocibles, con el macho de vistoso plumaje blanco en la parte superior y negro en la inferior, más la cabeza verde. Las hembras son famosas por las plumas de su nido (edredón), que se han recolectado en Islandia durante siglos para la fabricación de edredones. Habita en costas marinas del Ártico y el subártico.
