It's an iconic image, a glossy-green-headed drake flying above the lake on a summer morning, then skimming across the surface for a splash landing. Next, the quintessential duck call that is the mallard's quack. I snapped this picture of a glistening duck at Evergreen Lake.
The mallard duck is a very common bird around here. The female is a mottled, drab-brown that camouflages the duck while nesting. The most conspicuous feature is the iridescent, blue-violet stripes of color that can be seen on her wing. It's fun to watch them employ two completely different but equally humorous feeding strategies.
Head dipping is when they become completely upended with only their rump sticking out of the water. They don't dive but rather spend their time dabbling for food. If that isn't working, they take full of advantage of their neighborly relationship with humans. They waddle out of the water and cordially ask for food.
