6. Emperor Penguin
The Emperor Penguin is the tallest and heaviest species of penguin out there and is native to Antarctica. Penguins can survive sub freezing weather due to their heavy plumage, fat levels and adaptations in their hemoglobin to function when oxygen is low.. Penguins also can’t fly but they’re excellent swimmers who can easily hunt squid, krill, crustaceans and fish. Penguins can generally live for 20 years or even 50 years in some cases. These unique birds can reach about 4 feet tall in height and even weigh 50 pounds! Emperor penguins are also some of the most romantic species of birds as well. They are committed monogamists and will stay faithful to their mate for the entire year after the female lays an egg.

5. Greater Rhea
It makes sense that a large amount of the biggest birds on Earth are going to be flightless birds. It’s simple aerodynamics. The Greater Rhea is found in south america in countries such as Argentina, Bolivia, Brazil, Paraguay and Uruguay. However recently it’s been able to reproduce in Germany and revive the number of species. Although it doesn’t really seem like it should belong in Germany, they’ve managed to do fairly well and are even making up part of the habitat there. The massive birds can weigh about 60 pounds and be as tall as 5 feet.

4. Steller's Sea Eagle
Although this is american eye and as much as we would like to put the bald eagle on this list, the steller's sea eagle is the biggest. But we’re sure that bald eagle would win in a fight! This species of each can weigh about 20 pounds but the harpy eagle and philippine eagles. The steller's sea eagle is found on the Kamchatka peninsula in eastern russia, parts of Japan and the Northeastern Asian pacific in general. These cunning intelligent animals are great hunters and they dominate the skies. Although some other eagles come close to size, these eagles have much more pure lean muscle mass which makes them excellent flyers,. Their beaks are also quite impressive which are shaped like that for picking flesh off of bones. The massive wingspan is about 8.1 feet, making it able to match many vultures. This is one bird of prey you better pray you don’t run into in a dark alleyway.

3. Mute Swan
Mute Swans are swans that are generally less vocal and appear primarily in Europe, Japan, and the Eastern United States. This is the largest species of swan and it’s most recognizable attribute would be the little fleshy knob atop its beak which is normally larger for males. The can reach heights of 5 feet and have pure white feather except for the little part of black on the top of the beak There’s a population of about 500,000 mute swans after breeding season which doesn’t make it too but they’ve tended to decline in many places around the world. They generally inhabit in former soviet union countries where about 70 percent live. The mute swan was introduced to North America in the late 19th century where their numbers rapidly increased to the point where they were considered an invasive species. These were introduced by a conservation group who claimed that swans were indeed native to north american but this was incorrect.

2. Southern Cassowary
Another flightless bird, the cassowary is native to tropical areas in northern australia, parts of Borneo and you may have encountered this bird on rook island in far cry 3. These were once traded as a valuable commodity and their leather was used for various reasons. They’re often spotted with yellow or multicolored necks and are known to attack people when approached. They have very sharp claws on their toes. They can jump up to a meter in the air and will aim for your throat with their claws, so watch out! Southern Cassowaries will basically put their head down, run at you at full speed and with a thick helmet like skin on their head, they can guide themselves through dense forests without looking. There are less than 2000 cassowaries left and they’re slowly becoming extinct.

1.Ostriches
The two largest species of birds are the Somali Ostrich and the just plain and simple ostrich at number 1. Another fascinating large species of flightless bird, ostriches has extremely powerful legs which could easily knock you out with one good kick. Many believe that ostriches are close relatives to dinosaurs but gave up on flying once the dinosaurs were extinct. Researchers claim that since they lost a large amount of their predators, they simply became fat and lazy because they no longer had a reason to fly. Being the largest species of bird at 6.9 to 9.2 feet tall and weighing an average of 230 pounds, they also have the largest eggs of the bird kingdom. They set the record in 2008 for a confirmed egg weighing in at 5 pounds and 11 ounces! Some estimate that this egg would cost 40,000 dollars
