I have just started out with blender and i have become stuck seaming my UV map it seams to be right but its not layering properly

thats with the UV maps overlay

this is without the UV overlay

i dont understand why its missing that once piece out

thanks for any help

Check your image links

i would recommend to upload your blend-file directly to http://www.pasteall.org/ , because your images are bad, and it’s hard to tell what’s wrong on them. The only thing i can tell you for sure is:
your seams are not correct, because you have some bad stretching on the wings.
