What physical feature contrasts sharply with the male Common Yellowthroat's bright yellow throat?
Answer
Distinctive black mask
The male Common Yellowthroat possesses very striking visual characteristics that aid in species identification. The most notable combination involves the brilliant, bright yellow coloration of the throat area. This vivid feature is sharply contrasted by the presence of a distinctive black mask that covers the face. This facial marking provides a strong visual demarcation against the yellow plumage, creating the signature appearance of the breeding male warbler, even when only glimpsed briefly during a song delivery from a higher vantage point.
