Overall Color

Darker, lacking the warmer tones of Common. The warmest suffusion of buff coloration is on the nape

Brown wash on the underparts confined to the upper breast

Shows a very narrow (less than 5mm) white trailing edge to the secondaries, that just curls round and onto the inner web and tapers away

Underwing

Uniformly dark-barred underwing

Axillaries

Shows wide broad dark bars at least as wide as the white bars

Flanks
