Maybe you could try one of those traps that will catch an animal without harming it?? Put some treats in it that he can't resist.
I also agree with trying a net, but it won't do any good if you can't get at least fairly close to him. We have a pigeon that will let me get very close to it, but won't let me pick it up. When I needed to catch it a time or two, I used a net. It worked great!
I also used the same net today to catch a mean little bantam rooster fairly easily (so I could give him away to someone who actually wanted him). I would have chased that little devil a long time if I hadn't had the net.
