Almost empty nesters

We aren't, but the two very hard working swallowes living under our balcony are getting close.
The 3 fledglings had their first experience out of the nest today. I couldn't get much closer than this. They flew around a little and spent most of their day balancing on the trampoline net, mouths wide open, while their mum and dad dashed around satisfying their needs.
That bit sounds very familiar.
