Eliminating competition?

killing without eating will eliminate them too

If you kill because you are hungry, it seems logical you would eat your prey. If your prey doesn't actually provide nutrients, but killing them eliminates competition to nutrients, the behavior would be evolutionarily beneficial, even if not maximally efficient.

> Among primatologists, bearded capuchins are famous for using stone tools to obtain food. They’ve been observed placing palm nuts on a hard surface and smashing them with rocks to reveal the tasty kernels inside. Wild females have also been seen using sticks or blades of grass to pick their noses and eat any boogers they extract.

why would eating boogers be a selective advantage? They eat each other's boogers as well? the wild males are never observed participating?

Everything an animal does isn't a selective advantage, sometimes it's just not a disadvantage.

Conversely, when animals are scarce, wolves will eat lots of blueberries. https://www.startribune.com/minnesota-wolves-may-be-helping-...

Same with bears. For instance, the grizzly (brown) bears in Denali National Park who are farther away from salmon breeding areas (coastal areas) tend to eat a lot more berries than their coastal counterparts.

Fine, in that case, why is it a disadvantage for the males?

Now please don't tell me "it doesn't have to be a disadvantage for males, it might just be an advantage for females" !

Who said it was? Just because males don't exhibit a behaviour doesn't mean it's necessarily a disadvantage.

Once a horse gets a taste for baby chicks, it's hard to convince them they aren't omnivorous.

Horses are clearly and very much into the whole cowboy thing, they LIKE chasing down cows and catching them, some do it all by themseves and catch cows by grabbing there tails and hauling them around that way. Horses are panoptic motherfuckers and are startlingly good stalkers, which I learned living in close quarters with a horse needing to chase them away while doing stuff in the padock, but have them reapear, it took very precise sneeky peeking to catch them moving towards me, as they only move when I am not looking, which led me to the only viable deterance, which is to pretend that they are invisible/of zero importance which un nerves them, but so much as one eyelash of a look at them is taken as an invitation to partisipate, fuckers. Horses also work well with dogs, and for arabians in Arabia, dates and dried fish were used as feed for both. note, live with an arab/percheron cross far enough out that there is a wide representation of wild critters, and most everything is on most everythings menue, depending. And one of my more radicle, radicle friends would say, "we will eat the vegans first, they are slow and weak", refering to what to do durring an opocaliptic event, and until they could get out to my place in the country.

Its probably true of most animals. I raised a couple of pigs and we intentionally never fed them any meat, even though they'd probably eat it, because we didnt want them to get a taste for it

For sure they'd eat it - pigs have a taste for everything. You don't want to be the farmer who falls over in his pig sty.

Finally a time when this obscure Wikipedia article is relevant:

how do you explain the females do and the males don't? that sounds like a systematic occurrence
