i'll copy here the posts about this season so hang on a while till i'm finished.

Par melno stārķi - būvēšanas darbus plānojam veikt šo piektdien. Ja viss ies, kā plānots un nebūs pārsteigumu tehnisku ķibeļu veidā, nākamnedēļ šai ligzdai vajadzētu būt "gaisā".

About the Black Stork
We plan to carry out construction works this Friday. If everything goes, as planned and there will be no surprises in the form of technical kits, next week, this nest should be "in the air".

Thanks Liz!
Somehow I missed the connection.
We have 5 owlets in the nest. I am completely in love and almost can not see what is happening around me.

Nest Info (youtube)

BLACK STORK

The nest of the Black stork is located in the middle part of Latvia in Sigulda County. It is found before two years. The breeding area is known already since 1982. In 2005 previous nest was predated by marten, and, most likely, birds moved to the current nest afterwards. This nest has been built in a pine, on the branch 1.8 m from the trunk. It is located in boreal pine-spruce forest of an age between 150 and 200 years.

In 2017 a trail camera was installed at the nest. Four nestlings hatched and three of them fledged; the last fledgeling left the nest late in the season - on September 6, presumably due to belated start of breeding. The webcam is installed on 16 March 2018 by Jānis Ķuze, Jānis Rudzītis, Māris Strazds and Eduards Ozoliņš.

Virgin flight:
That's a bit difficult. Difficult because they have no rings. But by careful observation, I'm reasonably sure in the data.
26.07. two of them
27.07 one slipped and returned the day after
28.07 the fourth

Storklets last stay at nest:
The first starts his migration on August 8 at 13:23
The second on August 9 at 19:40
The third on August 9 at 19:40
The fourth on August 10 at 15:03

Gaja's last day in the nest was on August 9 at 14:02 (also the last feeding by her)
Kaupo last feeding on August 9 at 19:35

Kaupo has arrived on August 10 at 19:10
Kaupo starts migration on August at 5:56

The age of the Storklets at the start of their migration
Assuming that they leave the nest in the order of hatching, then
the oldest migrated at the age of 82,6 days
the second at the age of 83 days
the third at the age of 81 days
the fourth at the age of 80 days

EDIT 2018-04-13 ..is better it is on the first page. So we can find it easier.

Thank you Liana

1) Start of migration. Departure from nest does NOT mean immediate start of migration. Some birds do but many hang around for quite some time. This can be identified for tagged bird ONLY, all other „data” are speculations. I do not know what the english version of Vikipedia (in general poor source concerning BS) quotes but very likely those can be birds from western flyway – France and Belgium. Even if the figures are correct from the right sources, those birds are very different from eastern flyers (like ours or EE storks are), so cannot be used as a reference concerning thoughts „when will these juveniles start migration?”. Czech birds fly both ways so those data must be devided per flyway before quoting. Another important aspect is extra 1000-1500 km birds from LV and EE shall fly. It adds some time that they require to make it happen.

Data (unpublised so far) from 22 LV storklets that started migration at all (from 27 tagged), the mean age of start of migration is at least 89.7 days, min. 73.4, max 142.2 days. Of those 5 birds that reached age of 1 year, mean age is 90.5 days (Mellene – 92.5, Kate – 85.4, Sarma – 115.2, Raitis – 83.0, Mare – 76.4).

2) Small fish they eat now almost 100% is Neunstachliger Stichling / nine-spined Stickleback (Pungitius pungitius).

EDIT: M.S. both oldest storklets today are 80.6 (now) and 80...., not 81 (2018-08-06) it was wrong written in the chat

M.S.....Nest - this year they won't do anything since it makes no sense. It has been fallen down before this year at least twice - and has been restored in the same place. After winter nothing may remain there - if support branch remains, they might rebuild it within a few days. May not. This is actually very interesting document to see how it happens - as it has happened repeatedly in other nests too - exactly around the time of departure and in some cases has caused departure. It is obviously a good indicator of poor nest site (location in tree) wich in turn is indication of lack of good sites altogether.

.........this very interesting voice (+ behaviour) – bird points beak up, inflates beak sack and „hisses”
This behaviour happens again and again when some juveniles are in nest and some other juvenile arrives - what is important is the voice. I've never heard such one in other conditions.

There is a very interesting article by Maris Strazds on Goris. Distinguishing marks male and female.
My observation, that only the male sings, when he comes to the nest is correct.......
