About These Birds
Hill Partridge
Una perdiz de colina robusta (unos 280 g) propia de los bosques del Himalaya y del sur de China. Tiene un collar negro llamativo y partes superiores con vetas y barras complejas. Vive en laderas boscosas entre 1.000 y 3.000 metros de altitud, donde busca su alimento entre la hojarasca. Como muchas perdices, prefiere correr a volar cuando se alarma.
