Fig. 58. METHOD OF FEEDING THE YOUNG
From the above Table it will be seen that the hen was not relieved by the cock until a fortnight after she had laid her egg (in this case there was only one) so that probably she had been without food for a month. Then she left, and only returned to relieve the cock after the lapse of another fortnight, it being worth remarking that each was absent for the same length of time. When the chick was hatched, a different régime began, as of course the chick had to be fed and journeys to the sea made at regular intervals for the purpose of getting food.
When the chicks began to appear all over the rookery ([Fig. 56]), a marked change was noticed in the appearance of the parents as they made their way on foot from the water's edge to the nests. Hitherto they had been merely remarkable for their spotless and glistening plumage, but now they were bringing with them food for the young, and so distended were their stomachs with this, that they had to lean backward as they walked, to counterbalance their bulging bellies, and in consequence frequently tripped over the inequalities of the ground which were thus hidden from their gaze.
What with the exertion of tramping with their burden across the rookery, and perhaps on rare occasions one or two little disputes with other penguins by the way, frequently they were in some distress before they reached their destination, and quite commonly they would be sick and bring up the whole offering before they got there. Consequently, little red heaps of mashed up and half digested euphausia were to be seen about the rookery. Once I saw a penguin, after he had actually reached the nest, quite unable to wait for the chick to help itself in the usual manner, deposit the lot upon the ground in front of his mate. I saw what was coming and secured the accompanying photograph of the incident. ([Fig. 57.]) When this happens the food is wasted, as neither chick nor adult will touch it however hungry they may be, the former only feeding by the natural method of pushing his head down the throat of a parent, and so helping himself direct from the gullet.
