The parents are on the way now longer than before. The little ones turn into black. When one of them is moving, the nest is covered (full) . One of the parents seems to clean the nest in the back of the small ones.
10:35 and a bit later. Both parents were here. One of them were sitting on the handrail and this time so near on the right rim of part above that we saw him three times on the whole pic. The back we see on the left lower part and the head we see on the right part of this three parts.
Now I will show you movement in or on the nest. Both parents had come and the growing young ones were stretching and moving. I cut the pictures so have the nests nearer to notice the movement in a better way. I hope, it is not too much with the pictures. But the dark colours and the fact that we don't see the birds clear made it necessary to have many pictures to compare.
The time was 12:54 to 13:34
