I think more natural word order in English would be "Is it the same bird or another"?
Same or a different bird???
"Is it the same or a different bird" is an accepted translation.
I really don't appreciate having to make bad english translations to make this app mark it correct.
Very true. But it is not only native speakers who are DL users.
Isn't the DL App trying to teach Finnish language concepts, rather than perfect english grammar?
Still, I too would prefer to loose the bad english grammar wherever possible.
