Step 10: At the top, draw a long, pointy shape made up of two lines for the first feather on the cockatoo's crest. The longer you make these lines, the taller the crest will be. To the left, add another feather on the crest. The tops of the feathers should curve to the right. The bottoms should overlap a bit. Add two more feathers on the left side the same way. You can break up the line at the bottom for extra detail. Notice how the bird's feathers gradually get smaller and tilt more to the left the farther left they are.

Step 11: Continue to add more feathers on the left side along the top part of the cockatoo's head to complete the crest. Remember to gradually make the feathers smaller and more tilted the farther to the left they are. On some of the feathers, you can add an extra pointy tip at the top for another feather on the other side of the crest. Break up the bottom part of the feathers into short strokes for more detail. When you get to the bottom of the bird's crest, the feathers should be short and nearly horizontal.

Step 12: Draw two long, horizontal lines across the bottom of the body as a perch for the cockatoo to stand on. You can overlap the shapes of the bird's body but don't overlap the little ovals that are guides for the feet. The perch should be thinner than the ovals. You can make yours longer if you want.

Step 13: Darken the edges of the initial guides on the left side to create the first part of the cockatoo's body. Draw a series of short, curved lines close to the left edge of the body for the folded wing. The curved lines represent feathers. Add the tip of the folded wing at the bottom but don't overlap the bird's perch.

Step 14: Use the small ovals as guides to draw the cockatoo's feet and toes. Darken the outer edges of the ovals and split them in the middle to create the toes. Make the inner toe shorter. At the bottom of each toe, draw a curved, pointy shape for the bird's nails. Make the sides of the toes wavier. The toes should wrap around the perch, holding it tightly.
