What is another type of poultry that I can substitute for chicken (not turkey or duck)

The wife and I are hosting our first family holiday dinner and we want to make a type of poultry that isn’t chicken or turkey. The only other type of poultry I have had is duck, which I do not like.

What is a good substitute that isn’t too fatty or too gamy (what I don’t like about duck)?

Can you also please describe how that particular bird might taste.
