What immediately defines the bold contrast of the breeding male Whinchat's head pattern?
Answer
The face and throat are predominantly black, framed by an exceptionally broad, clean white supercilium
The breeding male Whinchat is noted for having the most visually striking appearance, particularly due to its head markings. The defining feature is the sharp contrast created by having a face and throat area that is mostly black, giving a mask-like effect. This dark area is dramatically accentuated and framed by an exceptionally broad, clean white stripe located above the eye, known as the supercilium. This broad white stripe is considered a highly effective field mark for confident identification of the male during its breeding season.
