Dear Edouard, You will find discussions about ducks identification, including dabbling vs diving ducks in WOELFLE, E. (1967). Vergleichend morphologische Untersuchungen an Einzelknochen des postcranialen Skelettes in Mitteleuropa vorkommender Enten, Halbganse und Sager. It is in German, as you probably noticed with the title. All the best, Quentin Quentin GOFFETTE Quaternary Environments & Humans Royal Belgian Institute of Natural Sciences Vautier street 29, B-1000 Brussels, BELGIUM +32 (0)2 627 44 33 De : Analysis of animal remains from archaeological sites [mailto:[log in to unmask]] De la part de Edouard Masson-MacLean Envoyé : 14 March 2016 15:57 À : [log in to unmask] Objet : [ZOOARCH] wild dabbling vs diving/sea ducks Dear zooarchers, Are there any osteological studies that have discussed morphological differences between wild ducks, especially dabbling vs sea-ducks/diving ducks. I have Ericson’s book on the eider but I was wondering if there were any other studies worth looking at. Also does anyone confidently identify dabbling vs sea-duck/diving or Mallard vs Eider, and if so on which elements? I attempted but saw too much variation to be confident enough but I may have missed the obvious for someone highly experienced with ducks. Many thanks for your help Edouard ----------------------------------------------------- Edouard Masson-MacLean PhD Candidate Room 119 Department of Archaeology School of Geosciences University of Aberdeen St. Mary's, Elphinstone Road Aberdeen, AB24 3UF Scotland, UK
