I have several theories concerning these two large ducks that have been hanging out around the old landing.
One is that they are at least partly domesticated. They keep their distance but don’t actually flee at the presence of humans.
The other is that they may actually be a cross between a Muscovy duck, which breeds with pretty much anything, and wood ducks. The colors on what I assume is the male duck are just gorgeous, and the female has that subtle blue-gray coloration going on.
