Whilst Alan is accurate as to the prompt for the report I suspect that the lack of a report at the time is because some people just aren't tuned in to listing, twitching, record submission, the birding 'scene' (if I can get away with using that term) and may have an interest in birds, birdwatching without it playing a major part in their lives.
It may well be with the increase in rare birds being reported in the mainstream media that more and more rarities will surface found by casual birdwatchers often after the event and we may need to get used to being gripped.
Oh and just to correct Alan slightly as I know he likes to ensure the accuracy of our reports, the excellent images that prompted the report were from
