What is the typical color of the bill in breeding adult White-crowned Sparrows?
Answer
Somewhat pale or pinkish-gray
The bill structure of the White-crowned Sparrow is typically thick and conical, which is characteristic of birds that primarily consume seeds. However, its coloration is a notable feature, especially in breeding adults, where the bill is often described as being somewhat pale or pinkish-gray. This paler bill subtly contrasts with the darker markings that may be present around the eye and on the face area. Observing this paler bill tone can sometimes assist in confirming identification, particularly when paired with other field marks, as it differs from the bills of some close relatives.
