Loons

There were 3 loons this morning on Black Canyon Reservoir.  It appeared to be a Common, black head,  and 2 paler juveniles.  Took some photos at great distance.  Went back this evening on a whim and took a few more.  Not sure these are the same individual.  The bills are very pale, and the neck blotch has a reddish brown cast when I enlarge it.  Any ideas?
