Mallard Duck - and a friend

I'm guessing this is a Mallard Duck.  As you can see, it hides well in this environment.

ISO 400, f/8, 1/500 sec, 400 mm

If part of the disguise is to sit next to a Heron, well that works too.  I passed over the duck a number of times when reviewing the shots of the day.  And come to find out that many of my pictures had hidden gems.
I like the busy green colors in this one.  The lines on the Heron show up well, as well as the yellow eye.  The branches add some chaos to the scene as well.  Busy works for me.  And the Duck.
