So... I've noticed that we don't get many birds at night (at our feeders). I'm assuming it is because birds sleep. I never did research on this but they have to sleep right? Where and don't they feel threatened?
Yeah, but it's harder to imagine for some than others. It comes down to how often we see the animal, mammal, or bird, I think. Of course they sleep, but unless you are in contact with them the majority of the time, it's hard to imagine them doing something you don't see them doing.I don't know of any animals that don't sleep.
