MAY 23, 2019 INFANTICIDE
Having started with this brood of four chicks we now have to witness brood reduction. It can be distressing to view so visual images of the attacks on the smallest, fourth chick were kept to a minimum. Links to pictures and videos are kept here. Three chicks hatched on 16th. May. The fourth, smallest chick hatched on 17th May. Forum observations and discussion from page 95 to 110.

I'm so very sorry to announce it.
At 20:59, Kati grabbed her youngest storklet by the head.
It was much worse than on May 21.

JUNE 20, 2019
Attack by a goshawk, which knocked one of the young black storks from the nest.
On June 22nd, Ain and Urmas visited the nest area and found a sad sight - the remains of the carcass left by the goshawk, Only follow this link if you are sure you want to see the remains.
Beginning on page 216 one can read all the somewhat unusual events of this year's ringing.
It was feared that the chicks may fall or fly from the nest. They did that.
Ringing was a little later this year as it was necessary to wait longer than is usual for ringing alone. This year both chicks were to have transmitters fitted, therefore the development of plumage had to be considered, too.
It took some long time to locate the chicks on the forest floor and eventually they were found, quite safe.
Departure from nest - 14.58 Estonian time
Caught on the groud . 16.18.
On return to the nest we could see that the ring numbers are
A surprise was that one of the transmitters is a deep reddish brown.(716A) Immediately, it was clear that the chick with the black backpack (7160) thought that the red thing was an intruder and should be attacked. Even more worrying was that Karl II thought the same - he kept coming to the nest but flew off again after a few seconds.
By the next day normal life had resumed.
Urmas posted a report of the event on page 230
Edit 31. 07. 2019
7160 has metal ring with code A 16386.
Body weight during ringing 2605g, wing length 475 mm, bill 126 mm.
716A has metal ring A 16387
Body weight during ringing 2650g, wing length 462 mm, bill 126 mm
July 22/23 the storklets made their first flight from the nest, later returning.
7160 flew from the nest age 67 days.
716A flew from the nest age 68 days.
. Kati seen on the nest for the last time this year.
August 4.. 80 days old.
About their ability to recognise close family members (p 269)
Visit wrote - was interesting, that Aru is begging to Oru - so i wonder how it is with the identification of each other or on the other hand the instinct to beg to other storks, even if it is a sibling...
Liz01 wrote - Also that they do not recognize each other at a certain distance, no matter if adult or juvenile.
Under stress, recognition becomes even more difficult (we saw it with Kati and Karl II)
Oru departed on migration on August 10. age 87 days.
Aru departed on migration on August 17 age 93 days.
Aru had sustained an injury beneath the left wing and some feathers were damaged. Posture and movements normal.
