I believe it is the mother who takes charge of the chick, and becomes so intensely jealous of it that she will not suffer even her cáro spóso, to whom she was so much attached, to come within a certain distance of it.

I feel sure, therefore, that only one does, and this one is much more likely to be the female.

The chick, in order to be fed, places its bill within that of the parent bird, and evidently gets something which she brings up into it. This appears to be liquid and, I suppose, is oil.
