Winter Birds

"Wake up, Rebecca, wake up!" My friend's little sister is yanking the covers off me. "Come on! You've gotta see this," she says, pulling me over to the guestroom window. "What am I looking at?" I ask groggily, scanning the Elsies' backyard and the Bras d'Or lake beyond. Then I see it almost directly in front of me, sitting still as a statue in the tree. My first Bald Eagle. We marvel at it in silence.
In a time when we are bombarded with sad stories about the destruction we cause to the natural world, there is good news here. Indeed the eagle has landed! Once a rare sight in most populated areas in North America, they are now almost common in some places. And Nova Scotia enjoys such a stable population that juvenile birds have regularly been transplanted to other places on the continent.
Public sentiment for Bald Eagles is at such a positive level today that it's hard to believe there was ever a time when they were persecuted. Farmers in particular didn't like them, and often took pleasure in killing them, believing them to be a menace to livestock. By the 1960s, Bald Eagles became conspicuously absent where they had once been common. And though the environmental movement had begun to alter people's perceptions of birds of prey, a much more insidious problem had begun to manifest itself. Widespread reproductive failure became apparent in a variety of hawks, falcons and eagles. This was later attributed to the use of eggshell-thinning organochlorine pesticides.
Austin-Smith says the improved public perception of Bald Eagles and their kin is probably the single most important factor contributing to their recovery. But what's more, people have begun giving the eagles a helping hand. In fact, helping eagles through the winter has become somewhat of a cottage industry in the Annapolis Valley.
"What the eagles do in the wintertime is scavenge. That's their modus operandi," says Austin-Smith. "They feed on this agricultural carrion (dead chickens) that's put out by the poultry farmers."
At Sheffield Mills in King's County, these feedings have turned into an annual event, attracting thousands of people in a single "Eagle Watch Weekend". During these feedings, it is not unusual to see 40 eagles sitting in a single tree. "People are willing to pay to see these things," says Austin-Smith. "Last year they had the Mounties there because of all the traffic. It was quite a sight!"
Although such winter feedings are by no means natural, they have undoubtedly contributed to the recent success of eagle populations. Mortality among juveniles is normally high, as they haven't developed the skills to find enough food to help them through the winter months.
"The first year or two of life is extremely difficult. Some of these birds are just out of their nests and they find it hard to secure enough food to get by," says Austin-Smith. "Essentially what we've done is we've given them an assist, a boost, so that we can get the population back up and going again."
Austin-Smith says that the Bald Eagles are doing so well that there is little more we need to do to maintain their status, other than to make sure we conserve sufficient habitat to fulfill their requirements. But as Austin-Smith points out, there is a danger that the Bald Eagle's plight will cease to interest the public.
