Thanks a lot for all your comments. I will answer to them as fast as I can.
Here, it is a picture of a crested grebe I did a long time ago in Paris....
The worse part is that with the work they did on this lake, this specie disappeared and is not nesting here anymore... to my personal point of view, it is a GREAT and a very sad loss to the capital.
Thanks for watching
And for the curious, the chick ate the fish without any problem.
Have a goodnight
