Who Pulled the Plug Out?

I am wondering if the boat at the front is a combination of a hero and a hooligan?

I had a chat to a member of the sailing club, apparently they will not be able to sail for a couple of weeks because high tide doe not coincide with daylight!

Because of the huge tidal range, they only ever get 3 hours sailing at the best of times.

It appears that I was a couple of days late if I wanted to photograph the Pied Wheatear which had been attracting enormous crowds of twitchers.

Apparently in twitcher speak, a Pied Weatear is a mega! Well I never.

I cannot help wondering what the collective noun for a crowd of twitchers is?

My guess would be a 'feather' of twitchers.
