I fully agree with Cliff's comments.
I remember a few years ago reading on the forum the Shore Lark and Snow Bunts were at S & T as I'd never seen the former before I decided to go, one of pals asked to go so I took her as well. On reaching the beach we had to look very hard to find the birds, as I had difficulty walking ( and still have) I plonked myself on my cow stool and my pal went further along the beach to find them, which she did about a hundred yards away.
I set up my scope and camcorder and hoped for the best! I thought to myself if I only get a record shot it's better than nowt.
I kept waving to her and she waved she back, probably letting me know I hadn't been forgotten. As I was deep in concentration I felt someone's presence, I looked up and it was JW, my pal and AR
come on they said we have come to fetch you and your gear closer to the action, which I thanked them for. Even though we were much closer than I had been we were still a fair way from the birds. There was quite a few birders/photographers there but none were upsetting the birds. Okay the birds did move a few times but that wasn't our fault, cos they rarely moved more than a few yards to eat etc.
I can't speak other than for myself and my pal but I got good footage from the camcorder and fairly good from my digiscoping ( using a Sony x3 zoom plus x25 Spacemaster) and my pal got decent shots with her DSLR+zoom. I was happy just to see the Shore Lark through the bins having never seen one before!
At the end of the day the birds should be allowed to feed wherever they decide to land be it in our garden or on the beach etc, who are we to disturb them in our quest to photograph/film them, without the birds many people would be devoid of an hobby including me, although I rarely go out these days.
Kind regards
