That goes double for your posts. If winter is supposed to be harsh, well, when the little animals emerge in the spring they seem happy enough. The birds and squirrels eat all winter, they don't know what this starvation thing is. Nobody freezes to death.
Your point is incorrect. The NT observation about the birds is correct.
Animals freeze to death all the time. Not all of them find shelter in time, and not all of them hibernate.

I suppose you mean Matthew 6:26. But that does not mean that birds don't fly into thunderstorms and suffer and die. I guess your point is that animals do not have the capacity to reflect and obsess and worry themselves sick the way we do, lucky for them.
But that doesn't mean they don't experience misery, however quickly they might forget it later -- assuming they survive intact. Even so, they develop Pavlovian responses to things, including unpleasant things.
In paradise you don't experience misery.
