Aw, shucks: More ducks.

Mary Ellen headed over to Cow Island Pond - the part of the Charles off Rivermoor Road in West Roxbury - around sunset and spotted this merganser with its butt seemingly on fire in the setting sun.

This time of year, the mallards are usually the main duck species at Jamaica Pond, but this June the wood ducks are giving them a run for their money - instead of the normal one mother wood duck and her brood, there are two, maybe three other families paddling around the pond.

In the dawn mist along the Charles River at Millennium Park this morning, Mary Ellen spotted a black crowned night heron, a couple of mallards and a great blue heron.

A family of wood ducks glided along the surface of Jamaica Pond yesterday.

A bunch of common eiders, including this guy, were bobbing around on the Sugar Bowl side of Castle Island this afternoon (thanks to Boston duck Twitter for the ID).

Mary Ellen journeyed up to Jamaica Pond today, where, amongst the fresh crop of hooded mergansers, which usually show up there about now, she spotted some redhead ducks, which are not commonly seen in 02130.

Sometimes, the pond also sees ruddy ducks, which, however, do not have red heads.

The mama duck and her seven ducklings had settled in for a snooze late yesterday afternoon among the mud and rocks along the Perkins Street side of Jamaica Pond, just up from that outlet tunnel. As the ducklings huddled in a big fuzzball, mother burrowed into her own feathers - but with one eye still on the water.

Then a heron landed maybe 8 or 9 feet away. At first, it stood there, seeming to eye the ducklings. Read more.
