Yes, the last of the three swiftlets in box 2 fledged. As you can see, box 1 non-breeding adults are still in residence as of first thing this morning and the two swiftlets in box 3 continue to thrive. In fact they're doing so well that one of them was actually doing wing excercises and flapping even though they barely have their eyes open. It looks like they're in a hurry to get up and away but that won't be for a while yet.
So will the adults from box 2 return to roost tonight or will they be away today as well? We shall see this evening!
