This weekend there were 3 hooded mergansers hanging around the channel in our backyard. Two males and a female. In the 5 years we have lived in our house it's the first time I have seen them here. We always get lots of mallards. They stayed right in the middle of the channel and when they saw me walking out on the dock with my camera they started to swim down to the other end. These pictures were taken with my 500mm and highly cropped. They eat fish like cormorants and anhingas and dive down in the water to get the fish. I hope they stay for the winter.
