Many people are familiar with a phrase that goes something like this: “He’s an odd duck.”
It is a phrase used to denote a person that is strange, unusual, or different.
Apparently the origin of the phrase is unknown.
Noun. odd duck (plural odd ducks) (idiomatic) An unusual person, especially an individual with an idiosyncratic personality or peculiar behavioral characteristics.
We suspect the phrase might have originated with the breeding habits of the Mallard. Mallards will mate with almost any other species of duck, and in the process produce some very strange looking or “odd ducks.” Mallards are so wide spread and their habits so consistent that strange “Mallards cross something” are quite common.
Here is an example of what might be the result of a Mallard cross something?

Mallard mixes are not the only ducks to have an odd appearance. For some reason the males of several species that spend a lot or most of their time in far northern Canada or off the coast of Alaska has developed very, yes, odd plumage. Anyone seeing these species might well have uttered the “what an odd duck” phrase.

4. Common Eider
A group of ducks called eiders take the cake when it comes to odd-looking ducks, however. Here are images of the males of the four eider species that are occasionally found in the U.S. The Common and King Eider can sometimes be seen along the east coast but they nest in far northern Canada. The Spectacled and Steller’s Eider nest along the Alaskan Coast.
