To post.... or to keep quiet?

On one of the better-known social media sites someone recently posted photos of a Rose-coloured Starling 'somewhere in Norfolk'. They declined to reveal its location which, to me, begs the question: why post in the first place? Surely a better strategy would have been to have shown the photos privately to a few friends - or keep it quiet. Lee Evans (quite rightly, in my view) gave the location of the bird - in a small village north of Aylsham - in a response to the initial post. Let's be honest: a RCS is never going to create a huge twitch, particularly given the current weather conditions: it's not even remotely as 'desirable' as a scarlet Tanager or Oriental Turtle Dove. Recent interest in the very tame Hoopoe in North Walsham didn't seem to create problems with locals, many of whom seemed keen to chat with the small crowd of birders it attracted...   (The photo below is of the confiding bird at Wells Quay a few years back)
