I recently came across terns in North Sulawesi: Some out at sea off Siladen Island and the others above Lake Tondano. Can someone help identify them?

Have you got any photos of them?

Michael.
Yes, and I thought I had attached photos (JPGs) but somehow they didn't get through when I submitted. The wifi here is terrible - very low signal.
Let's try again ...

The first is a juvenile Whiskered tern (or potentially a White-winged black tern if that is white on the rump) and the seconds looks to be an immature Sooty tern moulting into adult plumage, but it’s a difficult angle to evaluate.

I broadly agree, but would discount WWBT completely. The first bird is a juvenile Whiskered over WWBT in my view;
Broad wing bases,
Lack of dark carpal bar,
Chunky build and strong bill,
Head pattern - similar aged WWBT would have dark 'earphones' extending below eye.
Cheers,
