From hatchling to fledgling

"Our" little hatchlings fledged their nest today. A little promotion, hurray!
They are now wandering around through the buddleia. Not flying but hopping. Sometimes we can hardly see them; at other times they are clearly visible.
The parents continue to bring them food. And to distract other animals. We have more noise in our garden, as well as in the neighbouring ones. Especially papa blackbird sits far away. A hard time for them.
(With the fledglings not always being at one spot, like in the extra, I wonder how the parents can find them in the buddleia. Must have better eyes than me. And of course hear the little ones peep. One of both even started to practice some singing !)

PS: the two other eggs are still in the nest. I would have expected the mother to remove them.
