What color are the legs that distinguish a Willow Warbler from a Chiffchaff?
Answer
Paler, pinkish-yellow legs
A crucial physical differentiator used by field observers to separate the Willow Warbler from its close relative, the Chiffchaff, involves their leg coloration. Willow Warblers are characterized by possessing paler legs that exhibit a distinct pinkish-yellow hue. In contrast, Chiffchaffs have legs that appear significantly darker, typically described as dark brown or blackish. This specific detail, along with observing subtle differences in bill length and primary projection, forms the foundation for visual identification when vocal cues are unavailable or unclear.
