Roland Coombs noticed three ducks swimming on one of the ponds at The Sea Ranch golf course. They were beautiful Buffleheads, perfectly reflected in the water.
These ducks overwinter here on the Mendonoma Coast. They quickly dive underwater for tasty invertebrates. They nest far to our north. I find it interesting that they nest in old woodpecker holes, especially those created by Northern Flickers.
To hear their call, here's a link to the Cornell Lab of Ornithology: http://www.allaboutbirds.org/guide/Bufflehead/sounds
Thanks to Roland for allowing me to share his photo with you here.
