Persists?

I love how the title says "persists" when the information does not seem concrete. Almost in every paragraph, information is presented suggesting the ivory-billed woodpecker is not extinct but is followed by information that says it could be another bird. I think more strong evidence is needed before it is claimed the woodpecker lives. However, it is interesting how like everything, we as humans can blame ourselves for the decreased population of the woodpecker. Now there seems to be a big rush to recover the area and the woodpecker, however, if we didn't kill everything off in the first place none of this would be an issue. Anyway, I would love for ivory-billed woodpecker to still exist but i am not convinced by this article or the videos.
