At what stage is a hawk considered immature?

A hawk is considered immature until it gains adult plumage. This stage is significant because the plumage of a young hawk differs from that of an adult, which is an important distinguishing feature among species. Immature birds often have different coloration, patterns, or markings, making it easier to identify their developmental stage.

This distinction is crucial for falconers and ornithologists when assessing the age of birds in the wild or in training. Understanding the phase of immaturity helps in establishing breeding programs or in deciding the appropriateness of a bird for certain activities in falconry. The timing for maturation and the changes in plumage play a vital role in the health and behavior of the hawk as it transitions into adulthood.
