Why did people wear hats with feathers in the Renaissance?

In the renaissance people mostly ate wild birds. Because they didn't have guns, and most men couldn't afford a bow, they had to be able to get very close to the birds. By crawling as low to the ground as possible while wearing a hat with feathers, they were able to appear non-threatening to these birds. This let them get close enough to break the birds necks with their powerful teeth.
