Cape Cod Birding, Cape Cod Blog, Cape Cod Photography Red-Breasted Merganser At Pleasant Bay On Cape Cod Bay. March 12, 2021 Mel 1 Comment Post Views: 957 This Red-breasted Merganser was having a lot of success fishing in Pleasant Bay. He’d swim around a bit and then dive under… usually coming back up with a fish! I love his reddish-orange beak and his “bad-hair” day! Beautiful bird, don’t you think?
