Candidates for first national bird in tweets

Voting has opened to decide Britain's first national bird. The ornithologist David Lindo has begun a campaign for the honour to be conferred and an online poll has been opened.

Members of the public have until the day of the general election to pick their favourite from a list of 10, which includes barn owls, blue tits and blackbirds.

Here are the top ten - with a little help from Tweet of the Day.
