still can have two meanings in English: this was going on this morning and it's still going on – here you're speaking about time, so you have the temporal meaning. So if the moose keeps staring at you for a long time, then it's still = fortfarande.
I don't want to but I still have to – this most likely isn't related to time, but what you mean by still here is that 'I have to in spite of the fact that I don't want to. So if the moose stares at you even though it shouldn't, that's still = ändå
Hope this helps, or maybe I misunderstood your question in the first place.
