About a week ago while viewing the video feed it appeared to be just the one chick in the box, so after viewing previous saved captures I was able to see the first chick had fledged on the morning of the 23rd. After previously spending long periods of time at the entrance, an adult returned for a feed and soon after was followed by the youngster.
Now I knew there was an age difference after watching the chicks grow in the early stages, so figured it would be a few days before the second bird followed suit. It was in fact 6 days later before the second bird fledged and again following the adult around five minutes after a feed and around the same time in the morning.
Also from what I can tell from footage, it appears that just one adult remained with the second chick to feed and roost up. Which makes me wonder, did the other adult remain with the first fledgling to then begin it’s journey South? Maybe someone more knowledgeable knows but I find it interesting none the less. The adult did return with another feed four hours later only to find an empty box and with that an end to their first successful year raising young. Since then the adult has still remained and roosted and probably enjoying some last minute respite before it’s journey back to Africa.
The other two pairs I really don’t see much of other than hearing the chicks in the nest still at times but it can’t be long before they to go on to fledge.
