 snake fence, on stumps of trees and in all sorts of curious places. It is a 

 large, coarse structure made of twigs, roots, stems, grasses, dry leaves, 

 hair and wool. It is strengthened by a neatly-made cup of clay or mud 

 which is surrounded by these materials. We have often heard of spotted 

 eggs of this species. Breeds throughout its range.
