👉 Pachycephalus, which is a Latin word meaning "pachycephalic," refers to an abnormal or peculiar shape of the head and neck in some animals, particularly birds. This condition can be caused by various factors such as genetic mutations, hormonal imbalances, or environmental exposures. The term pachycephalus is often used to describe a bird that has a flattened or short neck, which may not have a proper alignment with the body.
