I think it is new young eagle (maybe experts can help with age)? Remo was very dark, now I think that he was hybrid Spotted Eagle (LSE and GSE).
I think last summer I was once musing about this possibility, but we never heard anything about it further. Maybe if the lab doing the genetic test on Tormi is finished, we will hear from Urmas if there is the possibility. But, remembering the LSE from the Latvian nest last year, they were all much lighter than Tuuli and Remo. I think the colour is like the colour of hair, some are lighter, some are darker, not like in WTE, who become lighter with passing time. Tuuli looks like last year, even that "curler in her hair" feeling is still there when she works on the nest
