How fast is the fastest bird in the world?

During a chase, however, speeds increase; ducks, for example, can fly 60 mph or even faster, and it has been reported that a Peregrine Falcon can stoop at speeds of 200 mph (100 mph may be nearer the norm).

Why do lights flicker in the distance?

When you stand on the ground and look at the stars, about 100% of the Earth’s atmosphere is above your head, so the light from stars has to pass through the turbulent air of the troposphere, where it is refracted, giving it a twinkling appearance. From an aircraft, this same thing happens with city lights.

Is ceviche raw fish?

Technically speaking, cooking requires heat, so ceviche (also known as seviche or cebiche), a dish in which raw fish is marinated in citrus juice, isn’t cooked. But it’s not exactly raw, either. Both heat and citric acid are agents of a chemical process called denaturation.
