the same stork started whistling at 09.05.46 for a short while (fanned tail feathers) and is moving the nest material (is some one nearby?)
it is male stork? (I need to review the photos from the previous days)
continuation:
09.10.04 again the same behaviour and again only few sec (approx. 20 sec)
09.12.28 again
stork looked around again
and at 09.14.38 enough suddenly stork flies out
