  High level of fledging activity recorded throughout the morning, with chicks 7201, 7202, and 7203 executing multiple flights and branch landings around the nest tree.
• Feeding Provision:
  An exceptionally well-fed day with 7 confirmed feedings (09:27, 09:35, 09:50, 11:20, 13:02, 13:31, 19:25), supported by the active fish basket, ensuring all 4 chicks - including 7202 upon its return - were fully nourished.
• Developmental Progress:
  Bonus (710L) demonstrated strong physical readiness through active jumping exercises at 65 days old, indicating potential maiden flight preparedness in the coming days.

Hello everyone

CHICK () +
- 1st chick: 69 days old (hatched in the night 21./22.05)
- 2nd chick: 69 days old (hatched in the night 21./22.05)
- 3rd chick: 6 days old (hatched on 23. 05)
- 4th: on 24. 05; brood reduction by female on 28.05 - 4 days old

- one chick, Bonus 2, adopted on 18.06

Leg Ring Identification:
Three of the chicks carry rings 7201, 7202, and 7203, while the adopted/foster chick (referred to as "Bonus") carries the distinct ring 710L.

Before their definitive departure for migration, the fledglings initially fly within an average distance of up to 200 meters, and as they get older, this distance increases to an average of up to 500 meters.

Better results are in surviving of the chicks which spend longer time in nest after fledging, means they return to the nest and step by step get independent, but are still getting food from parents in nest. For another 2-4 weeks after being able to fly they will go to the nest at night or rest at the nest.

Hello everyone

CHICK () +
- 1st chick: 70 days old (hatched in the night 21./22.05) MAIDEN FLIGHT .07 at ( days old)
- 2nd chick: 70 days old (hatched in the night 21./22.05) MAIDEN FLIGHT .07 at ( days old)
- 3rd chick: 69 days old (hatched on 23. 05) MAIDEN FLIGHT .07 at ( days old)
- 4th: on 24. 05; brood reduction by female on 28.05 - 4 days old

- one chick, Bonus 2, adopted on 18.06

Leg Ring Identification:
Three of the chicks carry rings 7201, 7202, and 7203, while the adopted/foster chick (referred to as "Bonus") carries the distinct ring 710L.


1/ By tracking 35 chicks with transmitters, Polish researchers found that these young birds permanently left their nests at an average of 87 days of age, with a maximum of 108 days. Before their definitive departure for migration, the fledglings initially fly within an average distance of up to 200 meters, and as they get older, this distance increases to an average of up to 500 meters.(Dr. Anderwald)

2/ Survival rates are higher for chicks that spend more time at the nest after fledging, as they return to the nest and gradually gain independence while still receiving food from their parents. For another 2 to 4 weeks after becoming able to fly, they will return to the nest to rest or spend the night. (Dr. Strazds)

3/ Fledglings learn to search for foraging sites and acquire food on their own only after their definitive departure from the nest (migration). (prof. Zielinski)
