The northern half of Green's Pond

The northern half of Green’s Pond




The Green’s Pond Conservation area in Fitchburg, Mass., is one of those small gems that are so often overlooked, even though thousands of people drive by it every day. Located between Ashby State Road and Rindge Road, it is small by any measure – just 28 acres, and half of that is taken up by the pond.

Originally, the pond was created as an ice pond. I can remember the old ice house still standing across the street back in the 1950s, when I lived not too far from there. A friend of mine and I would go fishing there, catching mostly perch and the occasional pickerel. My mother would make a fish chowder out of the day’s catch, something we all considered a treat.

Late one afternoon recently I decided to go back to the pond, hoping to catch sight of some migrating birds. A flock of mallards came onto the pond and started feeding and getting ready to settle in for the night. It was impossible to tell whether they were a migratory flock or not, since so many mallards now stay here throughout the winter.

A Great Blue Heron flew low over the pond. It had been feeding along the shore opposite to where I had been standing, and was no doubt heading for the perch where it would spend the night. Back when I was working for Massachusetts Audubon I was leading a family canoe trip on the SudburyRiver when a Great Blue Heron flew across the water in front of us. One of the kids pointed to the gangly bird and shouted “Look! A dinosaur!”

He wasn’t far from wrong. Great Blue Heron fossils dating back to the Pleistocene epoch, about 1.8 million years ago, have been found here in the western hemisphere. Elsewhere, some heron fossils date back 14 million years.
