Free Form Jazz

I work at a nature Kindergarten 2 days a week and have plenty of time to listen to and observe the birds in the woodland the children play in.  We have 4 very tame Robins who are always close by, and pop in and out of the polly tunnel where the outdoor clothing is kept.
Tweet of the day this morning introduced by David Rothenberg talked about the Robin being the bird world free form Jazz artists, which I liked very much.
