Yosemite Ducks These girls were up in Yosemite on the Merced River. The Common Merganser like most ducks in the park is not really a common sight. You are more likely to see a Mallard or a Canadian goose and not many of those. Val and I had the opportunity to see a mom Merganser and her babies up by Mirror Lake, all riding on her back . Those opportunities are rare and I feel fortunate to be part of the experiences. Have a wonderful day and stay healthy.
