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 Goldeneye
El pato chillón o porrón osculado es un pato buceador con el macho de cabeza redondeada verde-negro iridiscente y un pequeño parche blanco circular frente al ojo. Cría en bosques boreales de Europa, Asia y Norteamérica, anidando en cavidades de árboles. Cuando los patos vuelan, las alas producen un sonido silbante característico, de ahí su nombre en inglés 'goldeneye' (ojo dorado).
