Hi J.....these are based on the artwork of Sue Coleman, a Canadian artist. She incorporates Native art into her work based on the style of the Pacific North West native culture. In each of her animal pictures, she paints the subject and also the Native spirit of the animal....the one you are calling the 'ghost' in this style.
Her art is internationally renowned and reproduced in all forms. I love her cross-stitch interpretations. There are also lots of other birds in her gallery...maybe there would be another one your DH would like.
I intend to do a whole set of her pictures at some point...lol.
