What is the fine-grained topic of the following text: The wild turkey, Franklin wrote, “though a little vain and silly, a bird of courage that would not hesitate to attack a grenadier of the British guards, who should presume to invade his farmyard with a red coat on.” This very image of courage, with it’s massive size and impressive feathering, combined with its widespread presence throughout our country, and its central presence on national holidays, does make a strong case for the gobbling game. Only return the topic.
