A selection of headlines from stories in the news. Newspapers often use English in a way that you might think is intended to confuse, but it's all perfectly clear to the native speaker.
"That's Quite A Coo" was a used in The Daily Mirror for a picture story about a pigeon emerging from the window of a house with a bagel around its neck.
They used the word 'coo' because it's the sound a pigeon makes. Instead of the word 'coup' (a brilliant action, or as in this case newspaper speak for an exclusive picture or story).
