continuation:
- 13.10.03 they are noticing one adult stork, "food delivery" behaviour (it seems this stork is flying around the nest)



- this is usually the landing place of our female Kerli (the direction of arrival cannot be relied upon )

Chick Age (Days) / Action / Notes

20–25
Too early — avoid disturbance
Chicks fragile

25–35
Ideal for ringing only
Low risk of fledging

35–45
Ringing + possible transmitter
Monitor closely

45–55
Best for transmitter (if goal is post-fledge tracking)
Risk of early fledging

This later timing ensures:
- A better fit for the transmitter harness.
- Stronger body condition to carry the device.
- More durable feathers to protect from abrasion.
However, the trade-off is a greater risk of premature fledging or nest abandonment due to disturbance — so timing depends on specific project goals, site accessibility, and individual chick behaviour.
