Female Common Merganser
This bird really stood out in the crowd - the beak is vivid red, the feet the bright orange and the spikey brown head is also unusual.
Male Common Merganser
Green head seems common for ducks (Mallards obviously, but also American Widgeon's and wood ducks). In my mind, the female is just as showy as the male.
Mute Swans Looking For Seed
These are highly managed birds. Their wings are clipped (can't fly) and their eggs were addled (damaged so they wouldn't bear young) so they didn't proliferate. When the river otters moved in, they started losing fights and were relocated to a private property further up the lower mainland.
Two Mallards In Tight Skirmish
The duck on the right has the duck on the left by the tail. It's close to mating season for Mallards so the males are doing a lot of "positioning".
