I have no recommendations on a video. I was taught by a full-time taxidermist. I started out just skinning his birds for free, then worked my way to fleshing his birds. I soon was able to skin and flesh a bird faster and cleaner than he could do. I am just a hobbiest and am filling the North American collection right now. I do however skin and flesh for three full-time taxidermists, and do as many as 600 birds a year. I will tell you that besides understanding the anatomy of a bird, that fleshing is probably the biggest hang-up that a newbie will face. That's why I made the comment in the previous post on hearing about your first fleshing. They are thin skinned little buggers! Especially the puddle ducks, such as a Teal or Wood Duck.
Frank Newmeyer, Stephen Savides, and Dave Luke would be some Pros that I'd recommend trying to see if they have a video for you. Again, feel free to ask any questions. You may struggle trying to invert the wings or making the bill incision etc., and I have quite a bit of good experience to share with you. For further information on where to find videos, try going to taxidermy.net That is an awesome forum for Q and A's. Just remember to use the orange search button first, then ask if you can't find it in the archives. Good luck, Pete
