Regional Variation.<\/em><\/strong>\u00a0 Populations vary in the tones of their plumage\u2014but these variations do not appear to correspond closely to the subdivisions among forms that are sometimes recognized (i.e., \u201cEuropean\u201d, \u201cAsian\u201d, and \u201cJapanese\u201d).<\/p>

Skylark populations from southern and eastern Europe to central Asia (e.g., cantarella<\/em>, armenica<\/em>, and dulcivox<\/em>) tend to be paler than others.\u00a0 Those of eastern Asia (e.g., pekinensis<\/em>, lonnbergi<\/em>, and japonica<\/em>) tend to be darker overall, with warmer shades of brown.\u00a0 Those of northern and western Europe (e.g., scotica<\/em> and arvensis<\/em>) tend to be intermediate.\u00a0 However, each region or population seems to include representatives from across the spectrum of plumage tones.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
