Drawing something, like birds, actually depends more on your knowledge of the subject than on your drawing ability. And it is a deep and intangible sort of knowledge. Imagine your very wise birding mentor saying, “Yes, it is black with a yellow head…but do you really know what that bird looks like?” Drawing requires you to absorb details and then to combine them into a simplified and unified whole. Watching birds for countless hours is the way to get to know them, and drawing is the test to demonstrate that knowledge.
