I had not even heard of a pheasant coucal and I am not sure if I have seen one.
But I must have as they are found in many parts of Australia ( it is a sort of cuckoo and about 60 cm ) The Pheasant Coucal is found in dense understorey vegetation, , in open forests , and around wetlands, on farmlands with thick grasses and weed-infested thickets, such as Lantana. Often seen in parks, gardens and along roads or railway lines.
These feathers were probably picked of the ground in a local park or wetland area. They were in the box I was given by my family for Christmas. It was full of nature objects to draw - lots of feathers, seeds, leaves and a nest..
