Immature Gull on the Danube (1 Viewer)

I was out birding (to see Long-tailed Duck, actually) on the
Danube in northern Budapest this afternoon, and saw this
Gull amongst the many Black-headed and few Common Gulls.
I take it to be a 2nd Winter bird - either Caspian Gull (Larus
cachinans) or Yellow-legged Gull (L. michahelis).
Can anyone give pointers which might say which species it is?
Thanks for any help in advance
David

I have put this 2 two UK experts, and their opinion is that the long slender bill, white head and tail pattern both point towards it being Caspian Gull
(Larus cachinnans), which Gerard Gorman's 'Birds of Hungary' gives as being a faily common winter visitor, and very rare breeder.
