What will they think of next

Animals have plenty of weapons to use against us: teeth, claws, kicking hooves, horns... but they don't stop there. You think that bird droppings are only a threat to statues? Ask the members of the band Kings of Leon, who were forced off stage in St. Louis by pigeon poop:

The bassist Jared Followhill had already been hit several times during the first two songs, including in the face.

He said: "We had 20 songs on the set list. By the end of the show, I would have been covered from head to toe."

Andy Mendelsohn, the manager of the Nashville band, said: "Jared was hit several times during the first two songs. On the third song, when he was hit in the cheek and some of it landed near his mouth, they couldn't deal any longer."

And don't think bird poop is only a tool of music criticism: when a man in Sydney was killed when a shop awning fell on him, it may have been more than an accident:

It was known to contain a large quantity of pigeon droppings, from birds that had made the awning their home.

Some live birds and nests were even found in the wreckage.

The council is examining whether a combination of rain water and the droppings were too much for the awning’s supports to take.
