Weird..... Almost has the straight up an ddown neck and flat head of a runner duck but obviously is too big for that. Thats just what I thought of when I first saw it.
I am by far an expert but in my searches for Pilgrim geese and my purchase of them this weekend it looks like it is an inbred male pilgrim with undesirable grey markings. Are there knobs on the bill? It kind of looks like there are knobs running in a line on the bill by that photo. You can go look at photos of my males in my pilgrim geese thread to compare. Mine don't have the grey markings but some photos I have seen while searching had some of those grey in the neck and head.
I have a hard time discerning between Pilgrims and Toulouse however.
