Good Morning Eike
To help sustainably, ornithologists need facts. Governments, in turn, want evidence that a species is in danger. You can only prove that with data.
It is important to know what nutritional status they are in. By this you can tell if their habitat is good. Many data are collected. Not only weight...
When an egg is found, it is examined for harmful substances. the same by dead storklets in the nest or at the ground.
Here you can read about other nest and the results till now:

A quick look at the state of the 2018 Black Stork nests
By the middle of June, 19 "live" nests have been checkwd. Of these, in three nests birds aren't nesting.
Of the 16 nests, 4 are very late (layed eggs or just hatched chicks) = very bad;
The remaining 12 captured chicks (3.34 chicks per nest), which are very good, the best successful nesting figures since 1979 (but the number of nests is still small, see also the previous row; the closest results has been in 2011. g - 3.27)
None of the live chicks was weak, which is also very good.
Eight of these nests already have 12 unhatched eggs (the worst year since 1979, considering that there are still ~ 65 nests to be checked out).
One of the successful nests is completely new, previously unknown and is the only second-ever nest found in Latvia, which is not in the forest, but is in the row of trees surrounded by agricultural land on the river's edge. Details sometime later.
Examined nests include two of our search campaigns - the nest in the Rēzekne district is unproductive, most likely disturbed by the nearby logging (a loader from the other side of the felling that was exported in April and early May), the nest in Sēlpils is successful, with 4 chicks.
