Just two left now

Last night we had only three roosting, the two swiftlets and one parent bird, the other having left some time during the day. And then this morning, at 8.30am one of the youngsters left leaving only the remaining one in the box today. It has been doing it's wing excercises and peering out of the entrance and the remaining parent is still bringing in food, but we suspect that both will be away in the morning. Happy and sad at the same time! Here's the last of the swiftlets doing some wing excercies this morning:

It looks like it's trying to climb the box walls, and just look at that lovely fanned out tail towards the end of the video! Not long now....
