The term "wood hen" is not very common, and in fact, might refer to a specific bird species in some regions. However, if we consider it as a general term for birds that live in forests or woodlands, we can find several synonyms. Some of these include: forest grouse, woodland bird, timber fowl, bush quail, junglefowl, tree partridge, and so on. Depending on the context, the term might also refer to other animals or plants that inhabit forests, such as wood mice, woodpeckers, or wood anemones. As with many words, using synonyms can add variety, interest, and precision to our language.
