I realize this is the WCI chainsaw forum but you didn't say if you wanted to chainsaw it or not, if you do take a look on Youtube, there is a demo of a Pelican being chainsaw carved there, you also might get more results to your query if you ask on one of the numerous Chainsaw web sites, just do a Google on Chainsaw Carving.
Other than that the book, Carving Large Birds by Bill Dehos and Patrick Spielman has a pattern for a resting Brown Pelican . Unfortunately I think the book is out of print, but it might be available at one of the old book sites on the internet. You might also try your public library or a local woodcarving club library as well.
