I found this from another art blog:
1.Make cardboard wing templates for students to trace to keep the scale of the bird from starting out too small. The rest of the drawing was done with step-by-step instructions on the board. Describe the wing as needing to be tilted a bit, a “shark fin” was added on top, and a belly below. The black face looks a bit like half of a butterfly, and the beak extends directly to the right of it. A tail is added below, along with feet. The branch is behind the feet so it’s lines jump over the feet and tail.
2. After the drawing is done, it needs to be traced with a thin black marker.
3. Lastly, all except the snow is colored in with oil pastels.
