A young bird

I was doing a bit of a walk recce down the Machars today.I'd been told to keep an eye out for a certain bird.
Now I wished I had a big zoom lens.The white under the wings means it's a young bird,but the species is in no doubt.
After the bird landed he just sat on the rocks without a care in the world.I couldn't get any closer.
In sequence as he  flew over me. Apologies for the hazy pictures.

The following picture was the clearest.
