Hello :)

A physical adaptation is something that you adapt to over time and modifies the body.

In this case, aggressiveness is more of a psychological adaptation, migration is not something that modifies the body, and nor does a quiet bark. However, Hollow Bones were adapted over time that modifies the body that probably helped you adapt to the changing environments.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
