I first saw this unusual duck for the first time about two years ago. A pair spent about two weeks right out in the Oxbow Lake and close to my dock. What I noticed first was they were there one second and gone the next. Where?
Once I’d figured out they weren’t our ordinary Mallard, (it’s sometimes difficult to see them clearly as the light is often wrong and I only see a silhouette), I got out my Audubon Bird Book and plowed through it. It took a while to find the entry because I couldn’t see the colors, and they kept disappearing. A blink and they were gone! Then I saw one appear suddenly; the little rascal was a diving duck! That narrowed the field considerably.
The female is, I think, prettier than the male as you can see below. These pictures from www.ducks.org
The first year I spotted these ducks, there was only one pair, but last year we enjoyed watching two pairs fishing at the same time. It’s fun wondering where they’ll surface after a dive.
