August 7

Good Morning everybody :hi:

Michi, What a nice surprise that you are back. :2thumbsup:
I'm so sorry to hear, that you have lost a member of your family.
I figured, that your absence has something to do with your family, so I did not write here and asked what's wrong with you. I did not want to cause you any extra stress.
Big hug to you.

And thanks lot for your pictures and evening report. :2thumbsup:
5:26The storklets are still not at the rest of this nest.

5:34 the nest is hanging down on both sides

Email from M.S

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


thank you M.S.

hello! i have a question:
why are the storklets in Latvia still in the nest, while our storklets in Karula are leaving the nest. I thought the storklets in Latvia are elder?

and thanks for all your Reports!
I read them all! every day! :wave:

chrisitz, you're welcom :laugh:
I do not have an answer. Everything is speculation. Maybe the food situation in Karula is not so good. But at the moment both Storklets are in the Estonian nest. It is not describe why some start earlier and others later :puzzled:

Here are data by Maris Strazds:
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).

:hi: Chrisitz,
in both nest all the storklets fly and we see them on nest more or less time. In Karula now only Maru is away from the nest area. Usually the storklets still further cca 2 weeks are returning to the nest after the maiden flight. The youngest storklet, some times two are more often and longer on nest. And also they are nests where they come back the last days only to night. We know still not enough about black storks :bow: And they are all also enough much different in their behaviour.

Solo, they are almost in the same size here in that nest :laugh: I can not say which is the youngest. That's good :2thumbsup:
Otherwise yes, I also hope, that the youngest still gets a lot of food before it starts flying in the south.
