Ensconced on the ice, emperor penguins have largely avoided human efforts to hunt them, overfish their prey or encroach on their territory. Penguins face several threats to their populations, such as climate change, oil spills, illegal fishing, foreign predators, and plastic pollution. About two-thirds of the penguin species are listed as threatened on the IUCN Red List.

The blue penguin, ( Eudyptula minor), also called little penguin, little blue penguin, or fairy penguin, are the smallest of the penguins. Adults average about 10 to 12 inches in length and weigh between 2.2 and 3.3 pounds, with males being slightly longer and heavier than females.

Still, scientists familiar with the species say it’s common for a colony to experience the occasional bad breeding season. Jenouvrier S, Caswell H, Barbraud C, Holland M, Stroeve J, et al. (2009) Demographic models and IPCC climate projections predict the decline of an emperor penguin population. Proceedings on Natl Acad Sci U S A 106; 1844–1847. The colonies Fretwell observed aren’t large enough for this failed season to have a lasting impact on the species’ overall population, LaRue said. The bigger fear is that this collapse will turn out to be a bellwether for repeated failures in other colonies. Dr Jeremy Wilkinson, a sea ice physicist at the British Antarctic Survey, said the research “dramatically reveals the connection between sea ice loss and ecosystem annihilation”.

Bro I literally cheered so loud when the penguin made the leap over and slid to their homies,” wrote another.The smaller penguin species of the Antarctic and the subantarctic primarily feed on krill and squids. Species found farther north tend to eat fishes. For example, in Antarctica, Adélie penguins feed primarily on small krill, while chinstraps forage for large krill. While the larger species, including Emperor and king penguins, mainly eat fishes and squids. Large patches of brown guano – a buildup of excrement – on the white sea ice make emperor penguin colonies visible from satellites. Ainley DG, Clarke ED, Arrigo K, Fraser WR, Kato A, et al.

Foreign predators, such as foxes, dogs, and cats, are also threats to penguins. These predators often eat penguin eggs or harass breeding pairs, and in some cases, kill the penguins. In Australia's Middle Island, fairy penguin populations plummeted after red foxes were introduced and began to prey on the penguins.

Penguins: a group of aquatic flightless birds that live almost exclusively in the Southern Hemisphere. Penguins eat krill, squids, and fishes. Their diet varies slightly on the species of penguins, which have slightly different food preferences. This reduces competition among species.

Global heating is considered their main long-term threat, with projections that by 2100 about 90% of colonies could be so small that they are essentially extinct.

It is at present unclear whether this behaviour of breeding on ice shelves is a new phenomenon associated with recent climate change, or one that has always existed but has not yet been documented. Models of how animals adapt to climatic change exist [17] and we examine how this phenotype plasticity fits into those theories (see discussion). In recent years satellite observations have improved our knowledge of the emperor penguins breeding distribution [14] and population [13]. Here we report on newly discovered breeding behaviour in emperor penguins seen from satellite and aerial surveys. Four emperor colonies have been observed breeding on ice-shelves not sea-ice The first, discovered in 2009 [15]on the West Ice Shelf at the edge of Barrier Bay was a small colony of that could have been judged an anomaly or a break off group from the larger West Ice shelf colony located ∼110 km to the north. However, since the discovery of the colonies on the West Ice Shelf, three other, large colonies, have been found that are either permanently, or annually located on ice shelves rather than on sea-ice. Scientists are seeing changes off Alaska that have never been documented before, as warming upsets a vast ecosystem and one of the world’s vital fisheries. For the study, Fretwell looked at satellite images of five known emperor penguin colonies in Antarctica’s Bellingshausen Sea region, which saw a particularly stark decline in sea ice last year.
