Does the White-crowned Sparrow exhibit obvious sexual dimorphism in plumage?
Answer
No, males and females are very similar in size and appearance
The White-crowned Sparrow exhibits very little to no obvious sexual dimorphism in its plumage. This means that an observer cannot reliably distinguish between a male and a female simply by observing characteristics like the crown stripes or the general body coloration. Any subtle size differences that might exist between the sexes are typically minor and require physical measurement to confirm, meaning visual identification in the field relies on other consistent species markers rather than sex-specific plumage traits.
