What color is this drake?

[AngeJD]

Hi BYC experts!

Can someone tell me what color my drake is? I've been calling him a black magpie, but have had people call him chocolate magpie, ancona, east indies magpie (pretty sure that's not a thing) so I don't know anymore.

Not sure if pics show it, but his coloring underneath is definitely brown, but his cap is very green on top of the black. My hen is a gray mallard, and both ducklings from this hatch look like mallards as well.

Thanks!
