The ice on the harbor probably reached its greatest extent sometime yesterday. By the time I went out for a walk, the ice reached from the Maritime Terminal on the New Bedford side of the harbor to Fish Island; of course there was no ice over the deep channel between Fish Island and Pope’s Island; but from Pope’s Island the ice extended straight north to the point that lies just below the highway, and south to Crow Island to the boatyards and docks on the Fairhaven side. Gulls by the hundreds perched on the ice between Pope’s and Crow Islands, all facing into the sun.

I walked down to the hurricane barrier. An ice shelf extended from the hurricane barrier up to Fairhaven Shipyard, and bits of rotten sea ice floated on the ocean side. But by then the temperatures had climbed into the mid-thirties, and when I got back up to Pope’s Island, the ice no longer extended to Crow Island; scaup and Bufflehead swam where just an hour earlier the gulls had been perching on ice.

Even though today was ten or fifteen degrees colder than yesterday, even though the clouds moved in and blocked the sun, even though a cold raw breeze backed around from the north to the east, the ice had receded even farther when I went out walking this afternoon. I stopped on the swing span bridge to look at the extent of the ice down the Fairhaven side of the harbor. What caught my eye, though, was not the ice but a pair of Long-tailed Ducks swimming just below the bridge. I was impressed at how long they could remain underwater. I timed them on one dive, and they were underwater for fifty-five seconds. My sense was they could remain underwater even longer than that, but it was too cold and raw to stand there and time them again — cold and raw, as if snow or cold rain was moving in — so I walked on.
