Quick Answer
Juvenile Buffleheads have a speckled or streaked appearance, with white patches on their wings and a black back. Adult Buffleheads have a glossy, dark green back and a black crown, with a distinctive white patch on their forehead. The white wing patches of juveniles fade with age.
Identifying Juveniles
Juvenile Buffleheads can be identified by their mottled or speckled plumage, which helps them blend in with their surroundings. These young ducks have a mix of dark and light feathers, with white patches on their wings that are often more extensive than those of adults. The overall effect is a duller, less vibrant appearance compared to adult Buffleheads.
Key Differences in Plumage
The most notable differences between juvenile and adult Buffleheads are the color and extent of their white wing patches. Juveniles have larger, more extensive white patches that cover a significant portion of their wings, while adults have smaller, more rounded patches that are often hidden when the wings are folded. Additionally, the green sheen on the back of adult Buffleheads is a key distinguishing feature, with juveniles having a more subdued, brownish-black coloration.
