I'm not entirely sure specifically what 'jackals 2017 based on true story' is about as there could be many things with that name. It might be a movie, a book or some other form of media. If it's a movie, it could be about real - life events that happened in 2017 and involve 'jackals' in some symbolic or literal sense, perhaps related to human behavior or events in nature.
I don't think 'Jackals' is a true story. Usually, such titles are works of imagination or drawn from common themes and tropes rather than being rooted in reality.
Yes, there might be some documentaries or certain books that are based on true stories involving jackals. For example, in some wildlife research documentaries, they might show the real - life behavior of jackals in their natural habitats, which is based on actual observations by researchers. This can include how they hunt, their social structures, and how they interact with other animals in the ecosystem.
There was a story from a wildlife photographer. He was documenting the wildlife in an African savannah. He noticed a pack of jackals that seemed to be following a herd of wildebeest. As the wildebeest moved, the jackals were waiting for an opportunity. One of the wildebeest got injured during a river crossing. The jackals, true to their nature as predators, quickly moved in. The photographer captured this real - life drama which shows the jackals' hunting strategy based on opportunity.
