Mind if I get pedantic for a moment?
'Integument' refers to skin in general.  There's a word for the part of the
skin from which feathers grow:  pteryla.  The part of the skin from which
feathers do not grow is apteria.
You could just say 'the known scope for feathers', but if you're going to
refer to skin, wouldn't pteryla be more precise?
Hope you find this useful.
