• 10:22 – Feeding.
• 10:22:16 – The female arrived. Feeding, but it is not clear what she brought. The bonus chick lay down on the bottom of the nest and the oldest sibling stepped with its foot directly on its beak. It managed to free its head exactly at the moment when the female dropped the food. It probably did not get anything.
• 10:22:36 – The female flew away.
• 10:22:19 – 10:22:22 – It is clearly visible on screenshots how the oldest sibling holds the head and pins down the beak of the bonus chick with its foot.
• 11:33 – All chicks started calling together in a friendly manner. Is a parent somewhere nearby?
• 11:55 – A very small dropping from the bonus chick, just a single drop.
• 11:55 – The little one is not feeding well. Hopefully, the parents know where the fish baskets are.
• 12:18:30 – Ravens calling.
• 12:31:43 – A shadow passes by the nest, threat calls from the chicks.
• Surprisingly, both the chicks and the parents are tolerant of the foster chick, and it has already become accustomed to the other chicks. The main thing now is that it stops being afraid of the parents.
• It has been 22 hours and 40 minutes since the male last brought food/fed. This is concerning.
• It is hot outside, around 26–27°C. We need wet fish.
• Something is happening – the chicks are all looking in one direction.
• 12:41 – The chicks are having a "conference".
• If the male has really not been to the nest for 24 hours, it is time to start worrying about him.
• 14:42 – Strange voices/sounds can be heard.
• 14:45 – Feeding.
• 14:45:12 – The begging dance begins, even little Bonus 2 begs and eats. It is no longer afraid of the foster parents.
• The male has returned and brought the food.
• 14:45:10 – The male arrived. Feeding, but it is unclear if there was any actual food. Water was regurgitated, but usually water is given separately (once a fish fell out with the water). This time, there was only one regurgitation.
• The bonus chick rushed to hide at first, but then it was the first to try and grab the parent's beak.
• 14:45:35 – The male flies away.
• 14:45 – The male departed. When he arrived, the Bonus chick initially ran to hide, but then it was the first one to try to grab the male's beak.
• 17:20:07 feeding
• 17:19 – Female arrived. Feeding (fish). All chicks ate, and the Bonus chick was active immediately. The female departed at 17:20:14.
• 17:34:04 feeding
• 17:33 – Male arrived. Feeding (fish). All four chicks ate successfully. The male departed at 17:34:16.
Observation: It is very positive that the resident chicks are accepting the new (Bonus) chick well, and the parents are treating it well too.
