You must figure that, as rough as the cold weather has been for us, it’s worse for wildlife. Here, by the banks of the Housatonic, flocks of dark-eyed juncos, song sparrows, tufted titmice and black-capped chickadees have taken up residence in the boxwood — presumably because of its proximity to the breakfast bar. I no longer have a bird feeder after bears destroyed two versions and simply throw chili-flavored birdseed onto the snow twice a day. The tiny creatures from the boxwood are joined by blue jays, cardinals and a solitary flicker.

These birds will soon enough be nesting, and their babies will require a nonstop diet of caterpillars. This source of soft-bodied protein makes up more than 90 percent of native bird chicks’ diets, with each clutch consuming between 6,000 and 9,000 caterpillars before they fledge. That means we need a lot of caterpillars if we want our bird population to survive.
