I would spend most of the pages of an autobiography describing . . . an ant war. It is more intriguing and several things you could relate to the topic.
Henry David Thoreau seems to take a huge interest in nature and the writings of it. In Throeau’s autobiography he often strays to describe the scenes that go around him. The scenery, flying birds, and more. I’m pretty sure Thoreau would delight in writing about loons or an ant war but in my own writing, if I were a writer about life in the woods, I would most definitely write about both. As for which topic would take the most words is hard to say. When talking or writing literature on nature there are many ways to write about a single topic. Not only can you describe an animal, you can relate life stories to the animal or what it is doing. Take for instance, the loon in which I will instruct in Thoreau’s sense of writing. Describe the loon specifically (its colors, feathers, eyes, beak, webbed feet…)and what it’s doing specifically (swimming, flying, diving or fishing, ruffling its feathers, eating …). Join it with stories of anything that could relate to the loon or what it’s doing. Swimming, feathers, birds, or any stories you have to share about birds and the best: about loons themselves. Don’t stray off too far or you’ll get off subject, just enough to remind the reader that you are still on the topic of loons and make sure your reader won’t get lost. You can also include stories that you may have heard from other people. While you can write informational, you can also write in the future tense. Describe what you think it will do after it is done with whatever it is doing, what it will do at night, and so forth.
An ant war can be used in similar ways. Describe a lone pair of ants or a colony, the shine of their shell. Describe the intense or ferocity in their fight and what are the odds for one or the other. Again share some stories related to the topic, the ant bite, ant pile, infestation, pincers, or something else but stay on topic. Tell what it will do if one loses or one wins and if you have the details, go for an informational paragraph or two.
Now going back to the question “As a writer of an autobiography about life in the woods, would you spend more pages describing an ant war or loons?Why?”
I would go for an ant war. This can easily connect to other topics that I could share and many encounters that I can tell as well. I will explain everything I know about them and give a future tense of them if I were using Thoreau’s style of writing.
