All in a day's work

I believe this is the work of the robin pair who nested in this same spot last year. This was taken yesterday, started in morning and by afternoon looked almost done. This morning a mud lining is going in. That is my pink climbing rose in the way of the shot. I am letting it grow as tall as it can and so far it has passed the first story landing to the balcony. Last year the robin family did not have this added protection from predators and weather. More photos coming!
