subadult
Between young, grown
A subadult is an animal that has passed juvenile stages but isn't yet fully mature—old enough to leave parental care but not yet capable of breeding.
The term appears mainly in wildlife biology and zoology: The subadult eagle hadn't yet developed adult plumage.
As an adjective, it describes this transitional life stage: subadult males, subadult behavior.
