Mostly by sight. A cat can hear the high pitched flutter of a bird's wings that we can't hear. They smell them. A cat smells 14 times better than a person. A bird to a cat means one thing...It's dinner time.
For the same reason humans do: they occur, and we see, hear, feel, smell, or taste them. As hunting creatures who have evolved to depend on their senses, though, cats have much sharper senses than humans; they can hear better, see better, and smell better than the best of humans. When a cat startles at something you couldn't hear, that's simply because the cat's hearing is so much better than yours.
Depending on the cat's personality, then yes, it is possible for a cat to be scared of large birds. I have known of a cat to be chased away by a single crow. Some birds are naturally feisty or fearless, so will scare a cat away.
Aquatic birds
Usually no.
Cats do occasionally eat birds.
No, they're birds
When a mouse runs for cover in the presence of a cat the cat is an example of an external stimulus. Mice have an innate fear of cats, but the cat itself would be an external stimuli.

In one sense (colloquial) it can mean 'cat craze, cat mania, cat love'.
It's because of the food they eat. Inside cats are fed cat food, and cat food usually makes a cat gain more weight because some of the cat food ingredients. Now, a outside cat doesn't eat cat food. A outside cat eats stuff like mice and birds. Mice and birds don't have the ingredients cat food does. And outside cats have to hunt the mice and birds, and sometimes the cats don't catch the mice or birds. Sometimes it catches somthing sucessfully and sometimes it doesn't.
