Recognising mallard x pacific black duck hybrids

Came across this great article that includes an appendix with photos of several hybrid features, scaling them 1-6. 1-2 Being genetically pure Pacific Black Ducks, 3-5 hybrids and 6 being mallards. Features include facial markings, speculum features and leg colour. Can't seem to access the article via Notornis anymore so link to the facebook group's files.
