One thing to know about FromSoft games if you ever try again is they really want you to pay attention. They don't baby you with telling you what to do, but there are hints all around. For the bird on the bridge you can use fire for a ton of damage (molotovs are dropped by enemies in the area). I'm pretty sure item descriptions tell you, but also it tells you in the environment. In the street going towards that bridge there's a beast tied to a post that's being burned, for example.

The games really aren't that hard (except Sekiro), but they do ask you to participate. You have a lot of options to make them easier though, like using their weaknesses that are normally told to you, or summoning other players, or leveling up, or many other tools.
