Yes, there are several types of Scoter, and this plan includes two of the more common ones–the Surf Scoter as in the photo above and the White-winged Scoter. As a matter of fact it includes two body styles and male as well as female head patterns for both sub-species. There is a lot on information on this plan that measures 25" x 36".
This portion of the plan shows not only the profile of the body and head, but the extent of the hollowing, the ballast keel, and even the detailing of the drake's head. Everything included on the plan is life sized, so there is no need for you to estimate dimensions. Even with the anatomy shown, you are going to want good reference photos to paint those colorful bills properly. The end result is worth the effort, we assure you.
