The annoying thing about David Peters is that he focuses on random select species for his very broad cladograms, so in his head Spoonbills  are just classified as being “with storks” and moving them to be related to ducks only effects the spoonbills, when in reality this type of change in classification would effect the entirety of pelecaniformes and a lot of water birds in general
