Oh yea there definatly are. But your going to have to get used to using tutorials that arnt actually ment for wings. (Just look at the pics)
Here are some of my favorites
1.) http://maxrovat.sns.hu/subdiv/ (the best!, Teaches you how to do people)
2.) http://ambient-whisper.cgcommunity.com/Tutorials/facial/Page-1.html
3.) www.webreference.com/3d/lesson51/
4.) http://www.meshmaker.7p.com/ (the crash bandicoot tutorials taught me how to make legs, really helpfull!)
Hope that helps.
