I understand the point, but there is difference between seeing and catching.

And, that is one of the problems we are coming into in conservation. I have somewhat convinced a few non-hunting birders that it might be better for the environment if we hunted shorebirds (at least plover and curlew sized), cranes (including Whoopers) and swans (including Trumpeters). To hunt, you need large populations which require large tracts of habitat. To simply see (tick off on a list) you need a lot less land.
