Ostriches and penguins lack the ability to fly primarily due to evolutionary adaptations suited to their environments. Ostriches have evolved to be large, Flightless Birds that are excellent runners, allowing them to escape predators on land. Penguins, on the other hand, have adapted to an aquatic lifestyle, developing strong wings that function as flippers for swimming rather than flying. These adaptations have made flight unnecessary and even disadvantageous for their survival.
same reason as dogs they are lacking vitamins
Adelie penguins are not preyed upon by other penguins, so there is no reason for them to escape.
they actually walk normally for penguins, part of the reason is because they are adapted to move fast in water
If you were banned on Club Penguin for no reason, then it means that somebody lied to the moderators when they reported you and also because the ostriches can fly they have no more room for the bodies in the trunk.
The delta internet charge on your credit card statement is likely due to a fee for using Delta Airlines' in-flight Wi-Fi service during your flight.
There was no known reason to cancel the flight.
Some birds don't fly, like penguins and ostriches, but they survive. For birds that normally do fly, not being able to do so would cause them difficulties, in terms of things like getting food and getting away from where they were born. If they were born on a high cliff or tree, then it would be difficult for them to get away if they can't fly. They could fall and die or be caught by predators. So birds that normally can fly, but aren't able to do so for whatever reason, are more likely to die.
Penguins are hatched from eggs, not born through live birth -- which would be the only reason why a penguin would have a bellybutton -- but because they aren't, they don't.
One reason is to look for animals trying to steal their eggs. Another reason is to show excitement.
No. Emu meat is not considered kosher because emu resembles ostriches which are not kosher as well. (The rhea and the cassowary are not kosher for the same reason.)
Because there aren't any penguins around to hunt.
The main reason they are endangered is because we take their meal, which is fish. Now, biological scientists plan to make a fishing reserve for penguins only.
