Snow Petrel
Pagodroma nivea · also called snow petrels
Nesting on bare rock outcrops hundreds of kilometres from open water, a snow petrel is among the very few bird species ever recorded breeding so deep within the Antarctic interior, its entirely white plumage blending seamlessly into the surrounding ice and snow.
Overview
The snow petrel, Pagodroma nivea, is an entirely white seabird native to ocean and polar habitat across Antarctica and the surrounding Southern Ocean. Its extraordinary inland breeding range, all-white camouflage, and reliance on productive sea ice edges for foraging make it one of the most extreme and specialised seabirds found anywhere on the continent.
A bird that breeds where almost none do
Few birds anywhere attempt to breed as deep within Antarctica’s frozen interior as the snow petrel does, exploiting isolated rock outcrops far from the coast that offer safety from predators even at the cost of a long, demanding commute to find food at sea.
Status
Least Concern, remaining widespread across suitable Antarctic habitat, though closely tied to sea ice conditions that are changing in parts of its range.
Snow Petrel: common questions
How far inland can a snow petrel be found breeding?
This species is among a small number of bird species ever recorded breeding at extreme southern latitudes far from open water, nesting on exposed rock outcrops deep within the Antarctic interior, hundreds of kilometres from the nearest coastline.
Why is the snow petrel entirely white?
This species has entirely white plumage except for a black bill and dark eyes, an unusual degree of all-white colouration even among Antarctic seabirds, likely offering effective camouflage against snow and ice.
Does the snow petrel have any defences against predators?
Yes, this species can spray a foul-smelling stomach oil at potential predators or intruders approaching its nest, a defence shared with several other petrel and albatross relatives.
Why does the snow petrel rely so heavily on sea ice?
This species forages heavily around sea ice edges, relying on the productive waters associated with ice margins to find the fish, squid, and krill that make up most of its diet.
