Intuition In Animals

I write this on a Friday evening/night from my grandparents' house in the part of the rather large county of Lincolnshire closest to the Norfolk border. About this time or perhaps a little earlier yesterday, Grandad wanted to give some leftover bread (I think containing dried fruit) to the wild birds that normally visit the bird feeder or table. I told him you shouldn't give bread to the birds even if it didn't have fruit, because it swells up inside their stomach. He only responded that people have been giving birds for donkeys' years and it's only ducks you should not give the bread to, because it swells up when it hits water in the rivir or pond. He went on to say that wild animals are not stupid and won't eat food if it's poisonous to them. I said yes they would because they might not know the food is poisonous until they eat it, but he seemed to still think that they won't touch it by default. I got to thinking about it then and later and thought, that makes little if any sense. If someone doesn't tell you something is poisonous and you haven't found out through trying the food, how do you know if the food is poisonous? Yes you can use intuition and logic in part to decide not to eat the food, but on the other hand you could also decide that the food looks perfectly safe to eat and do so anyway. We all know that animals tend to use their intuition a lot more than most humans do, but even those lovely creatures don't know how to deal with the physical existence unless they learn it from each other. If you have little to no hearing and go to an area where birds are singing, you won't know that the birds are singing unless someone tells you so. Even if you see them flying or sitting around or whatever they're doing, they may or may not be singing, but because the physical sense of hearing doesn't work, you won't be aware of such a thing. You can of course go wherever you like and do whatever you like astrally, because the spiritual form is perfectly fine and has no limitations that are imposed on physical forms. That way you can go and hear birds singing or see the trees and animals etc, which then brings the question of why do we have a physical human experience if we have to rely on others to help inform and shape it or we have to look at things astrally anyway? I haven't yet found an answer, but still I wonder ... why are all of us spiritual beings having human, animal, tree, rock experiences etc? How and why did we end up on the planet known as Earth? As to animals, I know the horses and dolphins especially, but all of them in general bother with telepathy, intuition, empathy and whatever else way more than most humans do these days. I think this is partly because people choose not to, but partly because people find it necessary to condition each other into believing that anything other than physicality is imagination or made up.
