About These Birds

Madagascar Teal

El pato de Madagascar es una especie en peligro crítico de extinción endémica de Madagascar, donde persiste únicamente en unos pocos humedales costeros en el noroeste de la isla. Tiene plumaje marrón rojizo moteado con la cabeza rayada y un pico azulado. La destrucción del hábitat de los manglares y los humedales costeros, junto con la caza, ha reducido drásticamente su población.

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.
