In one sense, it could be stated that penguins do fly. It's just that they fly underwater, rather than in the air.
There are a number of reasons why penguins do not fly in the air.
Penguins eat fish. The fish they eat swim fairly deep under water, so flying is not an advantage in getting the fish, but swimming is. Therefore, penguins swim rather than fly. Quite simply, they don't fly because they don't need to.
Penguins cannot fly in air because their wings are too small for their body weight. Power required to stay aloft to counteract gravity is proportional to wingspan. Penguins have very small wings, yet are very heavy. The heaviest penguins are heavier than the heaviest flying birds. The heavier bodies of penguins are the result of their special bone structure and the blubber that they carry. The blubber protects penguins from the cold. Cold water can remove heat from the body much faster than air, so a good insulator is required. Colin Pennycuick calculates in his book "Modelling the Flying Bird" that a typical gentoo penguin would need to flap its wings 35 times a second (about equivalent to a hummingbird) to remain aloft. The penguin is simply unable to create enough energy to take off.
If penguins can't fly because they have such small wings, then why do they have small wings in the first place? The answer is that small wings are much more useful underwater because they have lower drag and greater agility. Their wing bones are fused straight, rather than angled like a flying bird's, and this has the effect of making the wing rigid and powerful, like a flipper. The small wings and a streamlined body shape are ideal for diving in water. Larger wings would create too much drag, while the small penguin wings are excellent for high speed swimming.
Unlike the majority of other birds, penguins do not have hollow bones, so are much heavier and harder to support with their small wings. The solid, as opposed to hollow, bones act as ballast to help them dive. Also, being solid, they are less prone to breakage from the stresses of swimming. Some (but not all) flying birds have hollow bones to be lighter.
Penguins also have higher levels of myoglobin and feathers optimized for the aquatic environment. Myoglobin is the main way penguins store oxygen during their long dives. The muscles of flying birds are filled with mitochondria and enzymes to power flight, and there is no space left-over for myoglobin. So, flying birds cannot spend us much time underwater as penguins because they have less myoglobin (less oxygen per body mass) and lower body mass (less over oxygen). Another benefit is that penguins are able to optimize their feathers for the aquatic environment. Penguin feathers are short and tight to keep water away from the skin and to create a smooth surface to lower drag. Flying birds have very different feathers that are fluffy to trap air for insulation.
because their to fat to fly that's the easy way to put it
because pengiuns are fat featherless birds. Their wings don't have a streamline shape and their bones arn't hollow, which puts more wait on them. Although penguins can't fly, they can sure swim up to 40 or 100 miles per hour!
Penguins don't fly because they don't have the right wing structure and wing feathers. Additionally, their bodies are very heavy compared to the size of their wings, and they are adapted for life in the water and a bit on land, not in the air.
There wings are too small to Cary there body weight
They can fly, but they would...well need to fly at plane speeds to fly perfectly.
Penguins catch fish by swimming to where the fish are hiding and catching them in their bill. They then swallow the fish whole.
Because it's too cold. They can't flap their wings. and b/c hawks will come and eat them out of the sky
Even though Penguins have wings, they are not for flying. They're wings are for helping them glide in the water to catch their food/swim.
They do fish. That is what they live off of and their bodies are perfect when they are in the water for catching fish.
If you know,PENGUINS DO NOT FLY
Yes, they are. Penguins are birds but they can not fly. However they still have feathers, are warm blooded and lay eggs.
There are a few birds that can not fly. Penguins are one, ostrich, and most chickens can not fly either.
why can penguins not fly
the vultures can fly and penguins can not fly
Where the Penguins Fly was created in 2008.
Penguins do not fly; they are a type of flightless bird. As a result, the question is not answerable as put. However, penguins are quite rapid swimmers.
penguins cant fly parrots can fly
The duration of Where the Penguins Fly is 2520.0 seconds.
No, penguins cannot fly. Their wing structures are evolved for swimming.No. They are one of the birds with feathers and wings who do not fly. They swim. Poor penguins.
