Birds say it with flowers

Now scientists have revealed that a species of bird has been growing flowers in an effort to attract mates.

Researchers, including academics from the University of Exeter, have found high numbers of potato bush plants near the homes of bowerbirds in Australia.

They believe the birds are unintentionally growing the brightly coloured plants by gathering them close to a site of habitation.

The birds are known for their unique courtship behaviour, where males collect sticks and objects to build a structure called a bower to catch the attention of females.

It is the first evidence of a non-human species growing plants for a use other than food, the scientists said.
