When do most species of Falconiformes come into adult plumage?

Most species of Falconiformes, which include various species of hawks, eagles, and falcons, typically come into adult plumage at around one year of age. During this time, young birds begin to molt their juvenile feathers and develop their mature coloration, which is crucial for various reasons such as attracting mates and establishing territory.

This timing is important as it aligns with their life cycle, allowing them to participate in breeding activities and contribute to the population dynamics of their species. The transition to adult plumage is a significant milestone in their development, marking the shift from dependency to independence in terms of survival and reproductive roles.

Other ages mentioned in the options do not accurately reflect the typical developmental timeline for reaching adult plumage in most Falconiformes.
