Greyhen, also known as grey partridge, is a species of bird that belongs to the family Phasianidae. This small, ground-dwelling bird is native to Europe and Asia and is known for its distinctive grey feathered plumage. Some synonyms for the word greyhen include grey partridge, Hungarian partridge, European grey partridge, and field partridge. These birds are highly sought after for their meat and are a popular game bird in many countries. Despite being a popular game bird, greyhens are also at risk of being overhunted, which has led to significant declines in their population numbers in some regions.
