A squab is classified as a young what type of bird?

A squab refers specifically to a young pigeon, typically one that is still in the nest and has not yet fledged. This term is widely used in culinary contexts, where squab is valued for its tender meat, which comes from young birds that have been raised for this purpose. While the other listed birds—duck, quail, and partridge—are also poultry and can be young or juvenile forms, the term "squab" is exclusively associated with pigeons in the culinary and farming industries. The focus on a distinct classification for squab underlines its unique place in food preparation and nomenclature, differentiating it from the other types of birds mentioned.
