Step 10: Use the triangular shape as a guide to draw the lower part of the heron's beak but make it thinner. Sketch the beak lightly at first and only darken the lines when you get the shape right.
Step 11: Draw the pattern on the head as a line that starts on the beak and curves over the eye and to the left. Break up the line into smaller sections to emphasize the feathers on the head. On the left side, draw a line that curves down toward the neck for the feathers coming out of the back of the great blue heron's head. Add another curved, broken line above the eye to complete the pattern on the head. On the left side, add another curved line for more feathers coming out of the back of the head.
Step 12: Use the remaining shapes as guides to draw the rest of the great blue heron's head. Make the shape of the head thinner as you darken the outer edges of the guides. Add a few more short strokes inside the head for a feather-like texture.
Step 13: Use the S-shaped line under the head a guide to draw the neck. Follow the path of the guide and lightly sketch the shape of the neck around it. The bird's neck should be thin, so don't draw the lines too far away from the guide. When you get the shape of the neck right, darken the lines. The bottom of the neck that connects to the body should be wider than the top part. Below the heron's neck, draw a series of long lines for the chest feathers.
Step 14: Draw the shape of the bird's folded wing inside the body. The bottom edge of the folded wing should follow the path of guides pretty closely. Use a series of thin, overlapping arcs on the left tip of the wing for the individual feathers. For the top edge of the wing, draw a series of short, curved lines that slope to the left side.
