     The owls (猫头鹰) were not what they seem, or so many people seem to think ...

     For centuries, owls have been feared and seen as signs of evil or death.But they are also seen as

symbols of intelligence. The bird's ability to see well in the night means that it is closely associated with

Athena, the Greek goddess of wisdom, She is frequently  described as an owl perched (栖息) on her

head.

     So humanized owls are often used to indicate that someone is intelligent and educated - a pair of

eyeglasses or a mortarboard, the square, flat cap worn by college graduates. According to an article in

The Guardian, owls are among the most popular birds in British culture. You see them in Harry Potter

series, delivering letters and parcels. They are also the stars of Legend of the Guardians, a 3D animated

film that cam out on September 24, 2010.

     Mark Cocker, a columnist (专栏作家) with the paper, notes that many TV dramas use owls. Why?

The answer, according to Cocker, is that owls belong to nighttime. It's a time of mystery. Owls fly in

silence, kill small animals for food and scream with a terrible voice. These facts made people associate

the birds with the dark and dangerous.

     Cocker believes that it is this "slight tremble of danger" that means the bird is often found on T-shirts

and bags. "Of all widespread British birds, they are still the species we hear most, but see the least,"

writes Cocker. "The owl reminds us as we lie in our beds that in the darkness…is a life and a beating

heart that we can never quite know."
