There are 20 types of bowerbird
They collect anything that catches their eye: beetles' wing cases, bottle-tops, even deer dung
They arrange these outside the bower to attract a mate
Some even "borrow" clothes pegs (colour-co-ordinated, of course)
Bowerbirds come from Northern Australia and New Guinea
Some more traditionally minded birds prefer flower petals and blossom to plastic implements
