birds

Beliefs which go back deep into (the) time lie behind many of our present-day attitudes to birds.
People have often regarded birds as having close affinties with mankind, because, like (the) humans, birds go on two legs, sing, show off and constuct homes.
Dances from many different cultures are copied from the courting displays of birds.
Some birds were thought to warn of disaster or foretell (a) good fortune, according to the circuimstances in which they were sighted.
In (the) parts of Scotand, it is still lucky to hear (of) the cockoo while you are out walking, but not before you have eaten (a) breakfast.
The Welsh used to believe that you would flourish if you were standing on (a) grass or green leaves when the bird sang, but if you were on barren ground you would not live (up) to hear its call another year.
Children in many parts of Britain still believe that it is unlucky to see (off) a single crow or magpie, but lucky to see two.
Birds were also involved in medicine: the ancient Greeks and Romans for example believed (in) that the way to cure blindness was to eat the heart of a reaven or owl or eagle - all (the) birds well known for their keen eyesight.

I have to put in brackets the words out of place.
