Thanks I was in need also how com some pics the look like a fleshy yellow?
the post of the pair of cans standing is a scanned photo of mine -- I have killed a few cans in my days and none have had a yellowish tint to them -- my thoughts are that they have more of a grey overtone for the fleshy part of the toes as you see with the single drake can photos
there are some taxis on here that have aviaries with cans -- perhaps one of those can help us out more ??
also, next time I am at the bird sanctuary I will see if the cans are up on shore and try to get some better shots of their legs/feet ---- those photos I took were primarily taken to get bird posturing
