My dad said he saw a Brumby eating a cigarette butt once and tried to intervene cause like Litter is Abhorrent, Nature is Precious, all that- and it got So aggressive with him about it that it spurred up ANOTHER Brumby into thinking it had something valuable and they started posturing and fighting over the cigarette butt
Because i had to go looking for a picture of these bastard horses myself, a share:
But i'd like to also point out: horses eating things they shouldn't and then fighting over them is just... normal horse behavior? They are not clever beasts.
