Mystery Ducks....Common Mergansers?

The same day we went out to the streams and lakes looking for ducks

that were migrating through our area,

and saw the Hooded Mergansers, we saw

some black and white ducks

which I cannot identify for sure

in my bird books....

This one had a head a lot like a Loon,

but it wasn't a loon.

This female was with him:

But then, when I saw her tufted head, we thought it might be another type of merganser...maybe the Common Merganser?:

The color was right for the female in this shot...she has a gray body and a rusty, tufted head.

And he was black and white.

But still, I wasn't positive.

He is very handsome:

They didn't stay long and quickly swam away, so that is all the photos

I could get of them.

So, bird experts...

what do you think?

Did I capture Common Mergansers????
