A little "Googling" came up with a few interesting leads. https://www.flickr.com/groups/444365@N25/discuss/72157629157445778/ http://www.10000birds.com/hybrid-teals.htm http://birdhybrids.blogspot.com/2014/04/cinnamon-teal-x-northern-shoveler.html
A nicely done paper that includes photos of a known-parentage, captive Northern Shoveler x Cinnamon Teal. https://www.researchgate.net/publication/324330231_Hybrid_Northern_Shoveler_x_Blue-winged_Teal_on_Schiermonnikoog_Netherlands_in_May_2014_and_identification_and_WP_occurrence Perhaps others can provide more data, but all of these would suggest John's bird is a Northern Shoveler x Cinnamon Teal.
