"... Urmas caught one unringed BS near the Jõgeva nest yesterday morning. It is possible that it is still stressed from the experience and has not yet returned to the nest. ..."

who know, maybe it is our male (or the female)

previous day (10.08) viewtopic.php?p=63489#p63489
next day (12.08)


August 11
Hello everyone :-)

CHICKS
- 1st chick: 79 days old (hatched late evening 24.05)
- 2nd chick: 78 days old (hatched early morning 25.05)
- 3rd chick: 78 days old (hatched afternoon 25.05)
Brood reduction by male
- 4th chick: 20 days old (hatched late evening 26.05)
- 5th chick: 17 days old (hatched afternoon 28.05)
prof. Zielinski (youtube chat info):
The direct cause was that male brought an insufficient amount of food, resulting in nutritional stress, which is the biological trigger that prompts adult birds to start the process of brood reduction.


MAIDEN FLIGHT
- 03.08.2026 at 16:22:45 a short flight by one of the storklets (? 70-71 days old)
- 04.08.2026 at 10:00 longer flight by one of the storklets (? 71-72 days old)
- (05.08 - 2 fledglings for sure, 1 stayed on the nest)
- (06.08 - all 3 fledged?)
- 07.08 - 3 fledglings for sure (empty nest) - 74 days old

FEMALE last noticed on 06.08.2026, MALE last seen on the nest on 09.08.2026

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)

📊 Events Timeline

Morning / Forenoon
07:51 The live stream restored functionality; three wet fledglings present on the nest.
08:59 One fledgling slipped from a branch and flew away from the nest area.
10:21 One fledgling departed the nest in flight.
10:42 One fledgling attempted to land on a branch but failed to perch successfully.

Afternoon / Evening
13:11 One fledgling returned to the nest.
13:21 A second fledgling arrived at the nest.
13:37 Both fledglings departed the nest due to human presence nearby.
13:55 Urmas reached the nest using climbing equipment.
13:57 Urmas placed fish in the nest.
14:01 Urmas completed the feeding intervention and climbed down from the nest tree.

Summary Highlights:
- Three soaked fledglings present on the nest in the morning following rain; plumage dried prior to departure.
- All three fledglings departed the nest during the forenoon.
- Human intervention: Urmas climbed up to the nest and delivered fish directly onto the nest.
- No direct feedings by adult storks recorded during the observed periods.
- Due to the disturbance caused by human movement and voices beneath the nest, the two fledglings present departed at 13:37 before the climbing began, and did not return for roosting overnight.

13:37:35 two storklet on the nest, they noticed the visitors (people voices) and flew away in hurry
the rope is climbing - food delivery?
action fish delivery by Urmas: 13:55:06 - 14:01:37

The male was last seen feeding the fledglings on the morning of 9 August. At that time, Urmas caught, ringed and fitted a solar-powered GPS/GSM transmitter to a black stork near the fish basket close to the nest viewtopic.php?p=63494#p63494. It was very likely our male, but this cannot be confirmed until he is seen at the nest again.
Today, Urmas brought a basket of fish to the nest for the three fledglings.
