Decades ago birds remaining in the Northeast in the winter almost exclusively survived on weed seeds and insects they gleaned from crevices in tree bark. Today, nearly one-third of American adults provide about a billion pounds of bird seed each year, to say nothing of suet, seed cakes, etc. Should we be worried about creating a population of food-dependent wintering birds? Studies suggest that this is not the case. Researchers (this is going to sound cruel) removed feeders from woodlands where Black-capped Chickadees had been fed for the previous 25 years, and compared survival rates with those of chickadees in a nearby woodland where there had been no feeders. They documented that the chickadees familiar with feeders were able to switch back immediately to foraging for natural foods and survived the winter as well as chickadees that lived where no feeders had been placed. Not only did the feeder-fed birds not lose their ability to find food, but research also showed that food from feeders had made up only 21 percent of the birds’ daily energy requirement in the previous two years. This is not to say that there aren’t negative aspects to feeding birds, such as window collisions, disease, house cats, etc., but one thing luring birds to our houses for a closer look doesn’t do is destroy their innate ability to find food.
