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)

Summary Highlights

• Feedings: 7 feedings recorded in total (Natalio: 4, Zica: 3).
• Nest Status: Fledglings aged 88, 87, and 85 days old[cite: 4]. High flight activity and frequent returns to the nest throughout the day, showing increased rivalry during feeding arrivals.

Daily Discussion Summary

• Debate on Chat Tone and Anthropomorphism:
  Chat participants engaged in a discussion regarding appropriate comments about bird behaviour. Observer Marika.Solo reminded members to maintain respect for the birds and avoid overly anthropomorphic jokes. Other viewers (including Adrian) agreed that the chat should focus on observing wild nature rather than personal arguments.
• Sibling Territoriality and Competition:
  Observers noted increasing aggression and pushing among the fledglings as they compete for space and food prior to their final dispersal.
• High Parental Investment:
  Viewers commended both Natalio and Zica for providing 7 feedings in a single day, ensuring the advanced fledglings receive optimal nutrition before migration.

"Aggression" = expression of adult instincts (defence of the nest as its own territory)
