F UZZY TARGETS of marauders, wild goslings run a gantlet of dangers and discomforts. Some eggs never hatch at all. Severe weather destroys others. Rapacious jaegers also take a toll. One of the hawklike seabirds (left) flies off, carrying an egg by the exposed embryo. Herring gulls continue the dive-bombing attacks when hatchlings arrive. A smaller winged pest perches on a gosling's bill in search of soft skin (above). Young geese at rest often obligingly pluck mosquitoes from one another. Alert for enemies, a goose takes her goslings down the McConnell River (below) to feed along the shore of Hudson Bay.
