Tootsi (2025) - Pärnu County, offspring of Kergu and Kerli

[marika.solo]

the autumn birdmap starts with data from August 15
The spring/summer migration stops in mid-August and the autumn/winter migration continues from the following day, the 15th = the bird map is set for autumn/winter migration and the new distance measurement starts from 15.08. However, the birdmap is sometimes ready a week or two later.

in this thread we follow Tootsi from the in Pärnu County - offspring of Kergu and Kerli (we follow Iksi's 1st autumn migration)

TOOTSI A16055 - colour ring number 719T, 1 CY
(CY = calendar year; birds are aged as the number of calendar years they have lived in, with the year they were born in as the 1st calendar year and increasing past every January 1st.)

birdmap description:
A young Black Stork that grew up in the Kergu webcam nest and started migrating on August 17, 2025 with another chick from the same nest (Vihm). The youngest chick (Iksi) was still in the nest at that time. The tracking device was installed on the chicks of this nest as part of the monitoring of the Black Storks of the Tootsi-Sop wind farm impact. According to the transmitter data, the fledged young birds did not fly to the wind farm area either during the flight exercises or during the start of migration. Tootsi and Vihm migrated together for the first two days (including crossing 150 km of the Gulf of Riga), after which their flight paths diverged in Lithuania. Tootsi's migratory instincts lead him to a more westerly migration route, but this may still change.
continuation:
Tootsi's migratory instinct leads him to the western migration route, but his migration route ended in northern Germany on September 10. The tracker data showed that Tootsi landed near Greifswald and did not fly again. He walked along the bank of the ditch for a few hours and finally died there. We could only see this from the data the next evening. Our colleague Carsten Rohde drove there the next morning and found Tootsi's remains. They were taken to the Greifswald Zoo and the police were also notified. The police issued a press release that an Estonian black stork had been shot in Germany - their initial observation somehow gave reason for such suspicion. However, Tootsi's body was taken to the Rostock research laboratory, where an autopsy did not identify the shooting, but an attack by a larger bird of prey. The bird of prey was probably an white-tailed eagle, from whose claws Tootsi escaped, but had to give up his life.

- The impact of predator-induced stress can persist even after the predator is gone, leading to a more generalised state of vulnerability that increases mortality risk over time.
- Predator-induced stress can significantly increase mortality risk, even without direct injuries.

Hello everyone

thx to our Madli for sharing

Tootsi – Last 3 Days
At the beginning of his migration, Tootsi was flying together with Vihm, but I haven't checked to see whether their later stopover locations still overlap. Today, around 17:00, the first new location points came in, but the transmitter updates are still pending — so more detailed data should follow soon.

Hello everyone

thx to our Madli for sharing

Tootsi is somewhere with poor signal and hasn’t sent any new data today.

Hello everyone

thx to our Madli for sharing

Tootsi is in an area with poor signal or experiencing GPS interference, so the transmitter has not updated yet.

This is what Tootsi's 8-day movement looks like on the Ornitrack migration map. There are anomalies, but perhaps the signal will improve in the future (up to Israel and Syria).
