As winter grips the Baltimore region, backyard birds that normally would rely on insects change their diet and will search for berries and other types of nourishment. The winter can make it hard for birds to find sources as snow blankets the area hiding natural food.
During bitter cold birds will fluff their feathers filling them with pockets of air acting as an insulation barrier. The more air they can generate, the better for them to battle the low temperatures.
According to Wild Bird Foods Unlimited birds need high-energy foods to keep their metabolic rate high. At times during the winter when food is scarce, backyard feeders can be especially helpful so birds can find a ready supply of food.
