We have lift off

All of a sudden all of the swallows took off early this morning. They were repeatedly flying out to the wire fence the other side of the road from their nest. One of the parents was keeping an eye on them and can be seen in the picture below sitting on the post. They were then all returning to the porch where they 'swarmed' around, sometimes hitting the glass of the front door, before returning to the nest...

They were still being fed by the parents despite being able to fly. I guess fly catching takes a while to master. One of them seemed a bit more reluctant to leave the nest and can be seen in the picture above. Eventually (s)he was flying and swooping as well as the rest of them.
