Emperor penguins bear the cold winter winds and they take care of their eggs in the winter season as well. The temperature in the Antarctic region can fall much below zero in the winter season. Bigger penguins might also push the smaller penguin by spreading their wings to look bigger and intimidating. Penguins also squawk loudly to scare away other penguins from their nest. As their flippers are solid, they can do ample damage.

Penguins will often fight other penguins by using their beaks and flippers to slap and hit the other penguins. Penguins can be aggressive when it comes to their eggs or their mates. Other times, penguins will try to steal other penguin’s mate if their own mate has not returned to the rookery for mating season. Sometimes penguins lose their eggs and they often try to steal eggs or chicks from other penguins.

Penguins often face danger from other penguins in mating season or when they are taking care of their eggs. Penguins are exceptionally agile underwater, and they use sharp turns and zig-zag motions to escape from predators in the sea. When trying to escape a threat on land, penguins often jump back into the water as they can swim away from the danger at a fast speed. This technique is called porpoising as it helps them to move out of the water at a quick pace. When exiting the water, penguins time their exit with the waves to make an explosive exit so that they propel quickly out of the water and escape the reach of any sea lions or leopard seals waiting for them. This camouflage keeps them safe from predators in water as well as in the sky. The white feathers on their bellies make them look like the sky from below, and the black coloration on their back feathers make them look like a part of the water from above. The extreme fluctuation in penguin population numbers highlights the fragility of the penguins whose survival is intimately linked to their environment.In water, penguins can swim fast to escape predators like sharks. These threats are exacerbated by an expanding human population and increased tourism to the Islands. As penguins are birds and need air to survive, the likelihood of them dying after having been caught in a net is extremely high. Bycatch has become a global issue for marine species as bad fishing techniques from all around the world have led to millions of animals dying after having been tangled up in nets. Human traffic on the islands, and especially fishing on the islands has also led to penguin fatalities. The same effect is feared to occur in Galapagos as the Galapagos, like Hawaii, is an isolated group of islands, so the introduction of a new disease can be fatal for a species that have no immunity towards it. In Hawaii, the introduction of avian malaria has led to so many extinctions hat it now has the highest number of extinct birds in the world, with ten extinctions in the last 35 years. A particularly virulent introduced disease is avian Malaria which is feared may eradicate the Galapagos penguin as it has done to endemic bird species in Hawaii. Humans have also brought diseases to Galapagos that the native species have no immunity against. Land predators are a great problem for penguins as their chicks cannot swim, making them easy targets for cats or dogs. Some of these invasive species include feral pigs, dogs, cats and fire ants, all of which predate on Galapagos penguins. Human activities on the islands over the last 470 years have inevitably led to invasive species being brought to the islands by colonizers, farmers and pirates. This means that less pairs can breed now compared to 40 years ago, so the recovery of the species is limited. Their nesting activities are also restricted due to many of the nests they used up to 40 years ago are now either prone to flooding or inhabited by marine iguanas.
