Brush-Turkey Trouble

These ecosystem engineers are thriving along the east coast of Australia. That’s just one message from Ann Goth’s new book ‘Amazing, Annoying Birds’, which explores these fascinating mound-building megapodes, expanding our knowledge about these much talked about colonisers of suburbia.
