Gull ID

[Rotarran]

Passed by DV this evening to check for gulls and there were some interesting birds there but being so rusty with gulls, I'm just not sure.  Someone did report a Great Black-backed Gull at Downsview but I'm not sure that's what I was looking at.  Help is appreciated.

This first one kinda struck me as being a possible juvenile GBBG.  


This next one I think is a juvie Herring gull but I'm not sure...big bird.


This last one I found kinda unusual due to no white spots on the wing-tips...is it still a Herring Gull?

All Herring Gulls. The 3rd is a 3rd winter bird transitioning into adult plumage, hence the lack of white spots. You can see both the black line of immature birds and the adult red spot on the bill.
