Along the beaver pond

Toward the end of the last month, we set up our game camera at the edge of the beaver pond. This is the first images we captured; more to follow.
These are either black ducks or common pintails, we are thinking they are common pintails due to the light colored edges of the body feathers and the possibly grey or darker beak. The black ducks should have a more golden colored beak and their body feathers should not be outlined in lighter colors.
Using the game cam has been the only way we have gotten images because they are very sensitive to intruders. Later in a day, we got the whole family cruising by (see below).
[UPDATE] We have now confirmed the species shown is a northern pintail duck.
