This photo pulls me in a very strange way, I almost going to jump in and take a look myself. Its all about what the little girl is visioning, she is inspecting with deep curiosity and great attention, it's more like their is a massage she needs to put together for the pigeon to deliver. Now the pigeon keeps a distance, sits and waits calmly yet ready in honor and reverence, as if the massage it is going to deliver is of an absolute fate. The parents feet facing the opposite side confirms what is happening is something of eminence considerably above and beyond earthly creature. We only see their feet, and so they are insignificant.
I am sorry if i went off to far, but this is the trip this photo gave me.
