How does the mature female Zebra Finch's beak color compare to the male's?
Answer
Paler orange
The beak color serves as a crucial marker in distinguishing mature sexes due to sexual dimorphism. The mature male Zebra Finch possesses a striking, bright red beak, which can also be an indicator of mate quality in the wild due to carotenoid intake. In contrast, the mature female exhibits a significantly duller coloration for the same feature; her beak is typically described as a paler orange compared to the male's vibrancy. This difference is maintained even in mutations like the White Zebra Finch, where the beak remains the primary sexual indicator.
