Shocking images reveals how birds are using human items to build their nests

Bowerbirds in an Australian city use a range of human items – from glass and plastic to banknotes and even a pair of handcuffs – to impress females, new research shows. Male bowerbirds create an intricate tunnel of twigs called a bower, then gather colourful items to show to any females that visit. The new study, by the University of Exeter, compared items collected by bowerbirds in Townsville City and a rural area, both in Queensland, Australia. City birds gathered larger, more colourful decorations – mostly from human sources – than their more understated rural rivals.
