Here is a strange duck

  

 

Nice color.

 

I thought it might be a Cayauga Duck, a specific domestic breed.  It's the right color, but the bill is wrong, so probably just another flavor of domestic mallard.  That's what most of the ducks we see in parks are, some version of domestic mallard.

 

Here is another bird worth a second look.  Snoozing, so we can't see the whole thing, but I think I recognize it.

 

Yes!  Another mute swan.  Didn't see that one coming.
