Not only the duty of incubation, but afterwards caring for the young chicks, is carried out not by one bird only, but by a dozen or more, which stand patiently round for a chance to seize either a chicken or an egg. Nor is it, as might be expected, the mothers alone who are seized by the passion of thwarted maternity; the fathers help their childless wives in their efforts to steal offspring. Every bird, male as well as female, has developed the “brood-spot,” and has the same bare patch of skin at the lower part of the abdomen against which the egg, when possessed, is pressed for warmth.
“What we actually saw, again and again,” states Dr. Wilson, “was the wild dash made by a dozen adults, each weighing anything up to ninety pounds, to take possession of any chicken that happened to find itself deserted on the ice. It can be compared to nothing better than a football scrimmage, in which the first bird to seize the chicken is hustled and worried on all sides by the others while it rapidly tries to push the infant between its legs with the help of its pointed beak, shrugging up the loose skin of the abdomen the while to cover it.… The chicks are fully alive to the inconvenience of being fought for by so many clumsy nurses, and I have seen them not only make the best use of their legs in avoiding so much attention, but remain to starve and freeze in preference to being nursed. Undoubtedly, I think that of the 77 per cent. that die before they shed their down, quite half are killed by kindness.”
It is from such an example as this that we may come to realise the extraordinary power of parent-hunger. Consider these penguin mothers and fathers clamouring and fighting for the possession of a child. With them the parental instinct has gained fierce strength from being thwarted. Is there not here yet another lesson for us to learn?
