Hello everyone

birdmap: They moved on from the Nemirov stopover in the same migration group on September 28.

Previous data
- 29.09.2024, distance: 2036 km (+ 88 km)
- MOLDOVA: Ciutești - a commune (Ciutești and Valea Nîrnovei) in Nisporeni District

NEW data:
- 01.10.2024, distance: 2323 km (+ 313 km in 2 days)
- ROMANIA: Giurgeni - a village in Ialomița County (Muntenia)

Alvar continued with Nurme, they spent the night "together" and ... (Nurme continued)

it seems not good to me

Most probably Alvar perished here because of collision with power line
birdmap: In morning 1st October flight of Alvar stopped just after power lines In Romania, while Nurme flew ahead...

I am very, very sorry for his lost

[marika.solo]

They are going to searching him tomorrow ...

... "it's from 29.09.2023, almost the same place (maybe 1km north or so) you lost Alvar now. This is a small small part of them." (author of the photo and this info is Mr. Catalin Pomeanu)

Alvar's remains (I have photos) - very sad view

I will not ask permission to publish - I do not want to publish them.
It was such a beautiful bird ...

[marika.solo]

detailed information and thoughts (email by Urmas and Cătălin) - some of them:

..... "The area is a rice farm and we met the manager by chance. We were lucky if I can say that because the bird felt in a portion they didn't use for the moment otherwise it will be flooded.
We discussed a lot about the situation and I asked also the opinion of Emanuel Baltag, the director of Agigea Bird Observatory, and we think it wasn't a collision with the power lines because the body was too far from the lines.
Poaching cannot be excluded but the opinions of the biologists are more inclined to believe that the bird has eaten something poisoned." ... (Cătălin)

... "Storks get injuries mainly on wings, if collisions with power lines happen. With falling they may injure also legs, but they are often able to walk after such incident, even several kilometres. Up to some predator notices that walking stork as a prey.
I have no proof that Alvar was walking, though. Rather both Alvar and Nurme were disturbed at night time so that they were separated. ... It happened about in sun set (between 18:34 and 19:02). ...Accelerometer of transmitter of Alvar shows anomaly in transmitter position since 9:44 (Oct 1st), when it shows transmitter being on side toward earth surface. ..." (Urmas)

Urmas described the "(most probable) scenario" in detail.

(Urmas asked if some eagles hunt migrating storks in that area - no answer till now )

so also the details:

"... At night transmitters are usually sleeping, so we have no data from night. Transmitters take GPS locations not simultaneously, but according individual schedule what depends on battery state and owners needs.
So Nurme takes locations after every 30 minutes, up to 19:46 and starts in morning 6:36; Alvar takes locations after every 10 minutes, up to 19:01 and starts in morning 7:15. Sun set in this area 18:48 (30 Sept, local time)

According these data I can say (most probable) scenario:
Something disturbed seriously overnighting Black Stork flock, where two tracked individuals were from Estonia (Alvar and Nurme). It happened about in sun set (between 18:34 and 19:02).

Because of that disturbance Nurme flew ca 1km north and stays there in (probably) rice field for night. Morning data start in the same place. He will not return to the disturbed place, but looks around in rice field edges up to 11:05. Somewhere 11:15 Nurme starts flying south, passing (in about 500m) the place Alvar finally stays (since 9:44, transmitter was not moving any more since 11:04).

Alvar flew only 150m from disturbed overnight place at 19:01 and there transmitter goes to sleep for night. Transmitter wakes up 7:14 about 770 meters westward (sun rise 7:02) at channel and roads between fields. Stays there up to 7:44. 7:54 Alvar is on field 820m SE direction, but 8:04 again at other channel and road along it (400m from previous location). Stays there up to 8:34. Next data 8:44 come 1,6 km southwards at the channel and road in the edge of rice field. Alvar stays there up to 9:34. Next data at 9:44 from his last location where Catalin together with his friends found remains of Alvar.

Accelerometer of transmitter of Alvar shows anomaly in transmitter position since 9:44 (Oct 1st), when it shows transmitter being on side toward earth surface. Changes in position of transmitter visible up to 11:04, but remaining day (up to 19:04, if goes sleep) it was not moving any more. Transmitter (and most probably the carcass) moved again since 10:34 next day (Oct 2nd) and often more up to finding it by Catalins team.

I have no good idea about perish reason. ... "
