What does a male Toulouse goose sound like?

[HENS-and-MARES]

I have 6 geese, 3 Toulouse, 3 Sebastopol. The Sebastopol, I know the genders of, the Toulouse, I have no idea. What does a male Toulouse goose honk sound like. Here are some pics of that helps. What do you think.

The same as the females. I find with mine the males necks are a little thicker and there is a bit of a size difference when they're standing side by side. Other than that I just wait to see who lays an egg or who mounts who then catch them and put a band on their leg so I know who's who

They are no longer laying eggs.

I’ve seen them climb on top of each other in their baths. Is the one on top male?
