First, he gets angry that no one believes him about the bird. Then he goes off and spends decades in solitude trying to find the bird alive. His attitude becomes more and more bitter over time as he tries and fails. Nothing's going to get in his way, so he can prove everyone wrong. It's become his Moby Dick, his sole obsession. Apparently he's murdered others in the past who have gotten in his way.
At first, he does think they are after the bird and he's wary of them, until he finds out that they are just a couple of lost people, an old man and a little kid. As soon as he finds out they've been in the company of the bird, he snaps back into his old ways immediately.
His characterization made perfect sense to me. The age thing, explanation or no, doesn't bother me.
