What distinct physical traits characterize the sexually dimorphic male Zebra Finch plumage?
Answer
Bright orange cheek patch, black teardrop stripe, and bold black and white chest barring.
Sexual dimorphism is strongly exhibited in the male Zebra Finch. Males possess several key identifying markings that females lack, including a conspicuous bright orange patch situated on the cheek area. Directly underneath the eye, a distinguishing black stripe, referred to as a 'teardrop,' is present. Furthermore, the male's throat and chest are adorned with clear, bold black and white barring patterns, distinguishing him visually from the more subdued female.
