Hi! I am desperately looking for some photographs or drawings of feathers from extinct birds (particularly recently extinct birds, as well as 1600 onwards). I suppose not all are documented but as many photos of feathers from extinct birds would be amazing. I am an artist, and i'm doing some work about extinct birds. i would prefer pictures of individual feathers if they exist. I am willing to buy a book if anyone can point me in the right direction. Much appreciated!
