Mono Monday - Alone

The Mono challenge today is to photograph something that stands alone.  This tall conifer stands in the garden of the Day Centre that backs onto our garden.  There must be a pigeon's nest hidden in there as one or other of the pigeons that visit our feeders land on the middle of the tree and dissappear inside.  If you don't happen to see it you would never know it was in there, apart from the occasional rustle of the leaves.  (The trees you can see in the background are in the street on the other side of the Day Centre }
Thank you to Carolina for hosting Mono Monday this month.
