Common Diving-petrel vs Snow Petrel: common questions
Which one can literally fly underwater?
The common diving-petrel is the one with this ability, using its wings to swim underwater in pursuit of prey, unlike the snow petrel, which hunts at the surface instead.
Which one breeds deepest into the Antarctic interior?
The snow petrel breeds deepest inland, nesting on bare rock outcrops hundreds of kilometres from the coast, while the common diving-petrel breeds in burrows on scattered Southern Hemisphere islands instead.
Which one is entirely white?
The snow petrel is the one with entirely white plumage, an adaptation for camouflage against its icy Antarctic breeding habitat, unlike the common diving-petrel's more typically coloured plumage.
