If they release fish, they will multiply and provide lots of food for those birds. So if a bird isn't hungry and goes by that fish, the bird will have the instinct to save it.

@@youtubeuser1993 human logic doesn't necessarily apply for birds

@Sheen023 Yeah, let me repeat what I said. "The bird will have the instict to save it" It's not a conscious decision because the bird doesn't even have a conscience. It's an instict crafted by millions of years of evolution.

@@youtubeuser1993 you need to acknowledge the conscience and consciousness at play here rather than throwing around words like instinct and millions of years...

@@youtubeuser1993 it's either deliberately put in these creatures or it's their own making
