This is a Long-Necked Duck (Goose) picture. It is apparently a goose from Hawaii because it has a ring of flowers around its neck. Any group of objects strung together with the object of being worn is considered, in Hawaii, to be a lei.
In machining, things are pretty much the same. Objects rub against each other and become worn. The wear marks have a characteristic pattern, depending on what caused the wear. The pattern of wear marks is called the "lay", sort of like the agricultural term "lay of the land."
But I figure, yeah, probably they have ducks in Hawaii. If those ducks are eating poi and pineapples and stuff, the ducks have Hawaii in them!
