A Tree House

Now that most of the leaves have fallen off the big tree we can see a nest.  There is an ongoing dispute between us as to whether it belongs to a pigeon or a magpie. I always thought that magpie nests were bigger and more ragged looking.  T says the pigeons don't decorate their nest, just lay down interlocking twigs. Well this nest has been decorated with leaves, so I think I am right. We need a referee, can anyone out there in blipland help.  I promise not to get too upset if you come down on T's side :-))  This has been taken from the ground looking up.
