Little Green Iguana

This small Iguana was in our backyard today.  He let my son and me get very close.  We took small slow steps until we were within about 8 feet.  He stayed quite still while I took several photos and then we backed off.  At the same time, there were many ducks on the water.  I snapped a photo of one that was not like the others!  (I know you sang that like the Sesame Street song!)

The duck below seems to have a broken bill and his head is definitely not shaped like the rest of the Mottled Ducks.  His body has the same color and markings, except for his tail.  He also seems larger.
