Turnips are good for hares, definitely. I've had badgers destroy my turnip patches, so, add them to the list.
Bogbean ROOTS are great for deer and elk. There may be other such roots that work but, so far, those are the only ones I've found. I suppose the reason for that is that, by the time I've researched an herb, I've usually bought or grown my own turnips, which I know works.
Lingonberries are bonafide as bait for birds, even if spoiled. Caught birds always eat the fresh berries in the trap. They never eat the spoiled, even though that is the bait that lured them into the trap. So I just reset the trap with the same spoiled berries.
I regularly catch birds using just a 'handful of rye seeds'. These they don't eat, either. I've tried some other seeds but I would not swear by them.
Here's the thing about loop snares and birds. One can't say that baits that are not eaten are good or not. I catch more birds WITH baited traps than with unbaited traps, but, I do catch them, sometimes, even without bait. Did they simply stumble into the traps? Can't say.
