Broadcast 16 December 1998, the penultimate installment concentrates on the ways in which birds rear their offspring. Having successfully incubated their eggs, the moment arrives when they hatch — and then the real challenge begins: feeding the chicks. Lapland buntings and dippers are shown doing so virtually non-stop throughout the day. The Gouldian finch has a further problem in that its tree-hollow nest is dark inside, so its young have conspicuous markings inside their mouths for identification. Grebes are fed feathers with which to line the stomach, and so protect it from fish bones. Coots and pelicans are among those that turn on their own and force death by starvation if there is insufficient food. The European cuckoo tricks other species into raising its chick, but it is by no means alone in doing this. Protecting a family is also a priority, and Brent geese are shown nesting close to snowy owls as a means of insurance, but as soon as the eggs hatch, they and their young must flee to avoid giving their neighbours an easy meal. The million or so sooty terns in the Seychelles prove that there is safety in numbers and the nearby predatory egrets have little success when attempting to steal. The behaviour of Arabian babblers is more akin to that of a troop of monkeys: they do everything for the benefit of a group as a whole. Eventually the day will come when flight beckons, and the grown bird will leave the nest to start a family of its own.
