Brewer’s Duck
The brewer’s duck is a cross between a mallard and a gadwall. It has dark feathers at the front and green coloration on its head and appears very similar to its mallard parent, though it’s definitely the friendlier-looking quacker.
Though mallards and gadwalls mate very commonly in the wild, their hybrids are not very commonly found. If you want to find one, you’ll have to seek it out for yourself; you might get lucky if you scour the ponds and rivers of the Lonestar state – Texas, USA.
