Good morning, mergansers

Some diving-duck “snowbirds” were swimming just off the west causeway park under the Ernest Lyons Bridge, Sewall’s Point this morning.

There were eight of these Red-breasted Mergansers. Here is a rare moment when all of them were on top of the water, not diving.

Fun fact from Cornell Lab of Ornithology…

Red-breasted Mergansers need to eat 15 to 20 fish per day, which researchers suggest means they need to dive underwater 250–300 times per day or forage for 4–5 hours to meet their energy needs.

The Red-breasted Merganser is a shaggy-headed diving duck also known as the “sawbill”; named for its thin bill with tiny serrations on it that it uses to keep hold of slippery fish.

The winter months are the best time to go looking for a Red-breasted Merganser, when they are fairly common along coastal waters in the United States and Mexico. Look for them in sheltered estuaries and bays swimming along in small groups or by themselves. Red-breasted Mergansers forage near the shore, so a spotting scope may not be needed to get good looks.

Snowy Egret too, brightening this windy rainy gray day.
