Another Year on Nest Watch

Last year I had Swallows in the small internal courtyard of my house here in southern Spain. It looks like they are back, but I can't tell if these are the original two or the chicks from last year. Have a look here and judge for yourself. They keep me company and are a welcome distraction form the pots. Today it is rainy and dull and this pair look a bit fed up with it all. Their clay nest is coming on although I think they are having trouble with it drying between layers just like me in the pottery.
