New-born hatchlings being fed
Parent of three hatchlings fighting off an intruder?
3-week old chick exercising its wings (with sound!)
3-week old chick defecating…
…and parent cleaning up
Watch carefully from 15:34:35.
Six videos from box #3
These were recorded on 8 / 9 July, when the three chicks were nearly 4 weeks old. The addition of a microphone reveals interesting details of swift life, including strange calls from the adult birds that I’ve not heard outside. It becomes clear that one of the chicks is much smaller than the others; it seems to be finding it hard to compete in the feeding frenzy that follows the arrival of a parent.
1. Big chick exercising its wings
2. Tiny chick exercising its wings
Compare the size of its wings with with those of big chick in the previous video.
3. Two course meal
The sound of the arrival of one parent sends the chicks into the usual feeding frenzy; then the second parent arrives. Towards the end one of the parent departs to collect more food – listen for the distinctive sound as it launches itself out of the tunnel, letting in more light.
4. Strange call…
In this feeding event, the difference in size of the chicks is again apparent, and Tiny chick is first to leave the mêlée. The parent (presumably) utters a strange call at 13:19:24.
5. …and again
This video begins with a clear view of the three chicks in the scrape, Tiny chick (with a much greyer face than the others) in the middle. The parent arrives, again with that strange call.
6. A quiet entrance
One parent is cuddling the chicks when the other parent makes a quiet entrance. The chicks pester it for food, but it’s not clear that any was offered.
