It’s not terribly cold. The temperature hovers somewhere in the mid-twenties Fahrenheit. No breeze ruffles the surface of the Mendenhall River. But the little dog and I are not designed for the conditions. So we adapt. Aki wears a knitted sweater with front sleeves that reach almost to her paws. She’ll shiver if she stops but she never does. Me, I am wearing gloves, knit hat, and heavy parka. My trigger figure numbs if I take too many pictures before returning finger and hand to their glove.
I wouldn’t have given any of this a thought if not for the great blue heron. He stands, still as one of the queen’s guards, in an ice-free portion of the river. He’s puffed out his chest feathers to trap warm air leaving his body but that’s all he can do to adapt to the cold. Around him mallards and golden eye ducks paddle, sometimes diving down to catch lunch. In the air above the edge of the wetlands, an extended formation of Canada geese flies noisily away. No warm parkas for them. I wonder if their kin provided the down that is keeping me warm.
A naturalist could explain all the things given to the wetland birds to help them tough out the winter. She could also solve the mystery of salt-water ice. Last night at slack high tide, when the beach we walk on was covered by seawater, a skim of ice formed. As the river dropped during the ebb the ice skim draped itself over tuffs of beach grass and beach pebbles. Brittle freshwater ice would have cracked and split when left by the tide to bear its own weight. But this paper-thin sea ice lays like a lover over the bent grass until the next high tide.
