That is one of the coolest things I've ever heard of a wild bird doing!Yes! The different species of Bowerbirds each collect a different coloured item. Satin Bowerbird collects blue items. Regent Bowebirds collect yellow items. Some species of Bowerbirds only collect white items and others only collect items that are a certain shade of brown.
At the sanctuary we only have the Satin Bowerbird and the Regent Bowerbird.
