Again, this seems like a timely place to remind people that there IS a list of what species require descriptions in the county. It is found at
http://www.lincsbirdclub.co.uk/lbc_recordsrequired.htm and can also be found on the LBC home page.
Note that the list will be updated in the very near future, but this one is close enough. Needless to say, Honey Buzzard is a description species (please ignore the brackets on this list - in the updated version it is full LBRC), so looking forward to receiving descriptions of the few HB's that have already been seen.
The status of Treecreeper at Dungeness is no excuse for not submitting descriptions from Lincolnshire!!

The list is available to view on here of what requires descriptions, and before the internet was around it was published in the annual reports. Plus until very recently, Great White Egret was a BBRC description species - a national rarity!
As an addition, BBRC see loads of descriptions by people we have never heard of. They are all treated on their own merits. A description by a little old lady will be accepted if it clearly describes the bird. Any records that are treated as not proven have not been described or seen well enough. This is the fault of the observer, not BBRC. We also find records not proven from observers who are very well known and respected. Everyone makes mistakes.
