That's a good story, nice to hear when the Police go out of their way to help people like that
One reason I try to avoid that side of birdwatching, I'm nowhere near the level where I could be sure of ID, especially birds of prey and waders... and warblers... and gulls... and...
But then although I get a buzz from new birds I'm too easily contented and loathe to travel for all that chasing about. :-O
I can see that once you've seen all the regular birds you might still want the buzz of the new and that may drive people to follow up rare birds but coming into the hobby purely to pursue rare birds as a sport seems to be where some (not by any means all! I'm not tarring anyone) of the problems occur as some people doing that aren't doing it through appreciation of birds but just to get the tick. As usual the small minority tend to get noticed and this blackens the reputation of the majority of caring twitchers who'd never dream of flushing a bird to get 'a tick'.
Just a guess but perhaps the social changes in the mid-80's had an impact, there was a lot of self-centeredness in some parts of society then!
