marika.solo wrote: 07 Mar 2022, 13:53... thx Madli, one week and she will be most probably on her streamed nest
I'm very happy that Skierka is going home: I hope that the cameras are ready to roll! 8-)
But Isn't she very early this year? I think that she will reach the nest before the male. Or is that normal time for storks to return to Poland?

it is normal for storks who are wintering in south and west of Europe ... (white storks wintering in Spain are already back on their nest e.g. in Germany and Czech. Rep.)
Skierka will be most probably the first - we will see. Previous season (her first nesting) they noticed both storks on the nest on April 18 https://youtu.be/dTJH4FXuj_w .

Notecka Forest: 30.03 male Notek, 08.04 female Nutka
Łódź: 02. 04. male Florentino, both on the nest 11.04.2021 - new female Fermina/2021 (there were broadcasting issues for several days)

"He just flew in"
One of our black storks has just arrived at the nest. We know about this fact thanks to the camera trap installed at the nest in cooperation with the Forest Experimental Station of the Warsaw University of Life Sciences in Rogów. Very early, because usually black storks arrive after March 15. If the equipment does not fail, we will observe the development of the situation and inform you about it on a regular basis.

LV, MARE - hafir dam

“Hafir” dams are usually small earthen reservoirs dug into the ground in gently sloping areas that receive runoff either from flood flow diverted from streams or from large catchment areas. Generally, they have a volume ranging from 500-10,000 m3 and are used to store water for human and livestock consumption. Hafirs are located in natural depressions and the excavated soil is used to form an embankment around the reservoir to increase its capacity. Wing walls and improvements to the catchment apron may help to increase runoff into the reservoir, but seepage and evaporation are often high in the dry season."
(http://ikp.nilebasin.org/en/document-re ... anual-no-3)

"It rains a lot in the rainy season but the water goes lost, in the region of the White Nile in Sudan.
A local solution to catch this water: Hafirs. An ancient technology since the Pharaohs times. We would like to develop these and build them where they are needed.
In the region, groundwater is too saline to be uses as a source of water and there are no pipelines connections to the Nile So there are only the Hafirs left and we want to help building then :-)"

Thanks Marika for the interesting info. :)
For me, it is a big mystery when even young storks that have never migrated meet at such feeding grounds...
