Why
Gould describes the bill as 'light horn-colour, the tip tinged with vinous', and the plate paints a horn bill with a pink tip; the bill tip is reddish in the Northern Giant-Petrel and pale green in the Southern at every age. Gould's prose takes in both species (his white 'albino variety' was a white-morph Southern), but the figured bird is a Northern.
