What happened to the mini boss that flew in by eagle?

I'm playing dark souls 2 and I've gotten to the part where I'm stuck in between the first mini boss of Cathedral of Blue and going to no man's wharf. What I've found out that I can skip no mans wharf together (my walk through is telling me about all this crap that I have to go through and there isn't even items that'd I want) but it also tells me of this other boss in forest of fallen giants, but I already skipped him by falling off the pedestal and now he will not respawn, please is no mans warf easy to get through or is it better to find a way to get the eagle boss to reappear and beat him. Or can I just altogether skip the boss and find the so called eagle nest? And if it's worth anything I'm a melee character and I've already defeated the Last Giant.
