The Galápagos penguin is therefore found in both the Southern and Northern Hemispheres.) (The Galápagos penguin is found on the Galápagos Islands, which straddle the Equator. Only one penguin species, the Galápagos penguin, is found in the Northern Hemisphere.
You can find out more about penguins that live on Antarctica on this page: Antarctic Penguins.Predators of penguins include sharks, killer whales (orcas) and leopard seals.Īlthough many penguins live on cold, inhospitable Antarctic and subantarctic coastlines, some penguin species are found in temperate regions further north. Penguins hunt at sea, using their excellent swimming abilities to capture their prey, which includes ocean animals such as krill, fish and squid.
(While a penguin is swimming, its pale undersides conceal it against the sky, while its dark back conceals it against the sea bed.) The black and white coloration of penguins is an example of “ countershading” – a means of camouflage that conceals an animal from both above and below. A penguin’s powerful wings are adapted for “flying” through the water rather than through the air. Although penguins have lost the ability to fly, they are skilled swimmers. Penguins are aquatic, flightless seabirds in the family Spheniscidae.

On Macquarie, euphausiids make up only half the diet by weight, with fish constituting the other half.FREE printable penguin question sheet: click here or on the image above to view / download your copy! (No log-in / sign-up required) What Is A Penguin? The diet is mainly composed of crustaceans. Royal Penguins have been recorded, possibly breeding, on Heard, Kerguelen, Crozet Island, and Marion Island amongst dark-faced Macaroni Penguins and stragglers have been observed as far north as North Island, New Zealand. Vagrant dark-faced birds are known from South Africa, Antarctica, Campbell Island, and The Snares. Macaroni Penguins are migratory and found only exceptionally near land during the non-breeding season. Breeding colonies are found on the Antarctic Peninsula, islands around Cape Horn, Falklands, South Georgia, South Sandwich, South Orkney, South Shetland, Bouvetøya, Prince Edward, Marion, Crozet, Kerguelen, Heard Island and Macquarie Island. The range overlaps with that of the southern form of the Rockhopper Penguin. The distribution of Macaroni Penguin extends from the sub-Antarctic to the Antarctic Peninsula, but overall they are found further south than the rest of the crested penguins. Satellite telemetry studies indicate that Macaroni Penguins forage mainly along the polar front regularly travelling up to 400 km to reach a feeding site. In most cases the A-egg is lost before or on the day the B-egg is laid, and it almost never survives to fledging even though the embryo is viable. The first-laid A-egg is about 61-64% smaller than the B-egg. Egg-size dimorphism of Macaromi Penguins (and Erect-crested Penguins) is amongst the largest known for any bird.
Most birds build a small nest from pebbles and by scraping out some mud or sand, but many pairs are content with laying their two eggs on bare rock. Instead only a short orange-yellow supercilium is present.īreeds on rocky slopes, beaches and amongst tussocks. Immatures are similar to adults but lack the long feather crest.

Most Macaroni Penguins breeding on Macquarie Island (south of Australia) have a white face and are referred to as Royal Penguins: they are sometimes given full species status ( Eudyptes schlegeli), although the biological basis for doing so is very doubtful. Macaroni Penguins are also slightly larger than the other crested penguins. higher up the head than in other species. They originate from a supercilium that meets at the front, i.e. In contrast to the other crested Penguins, this species has orange, not yellow, feather plumes.
