The middle of December always seems to be one of the best time for rarity finding, no doubt because nearly every birder on the continent is out participating in Christmas Bird Counts, freed from local patches to cover those 15 mile across circles with redoubled intensity. It's these sort of exhaustive area counts that really seem to turn up the rarities, as those birds are generally present, it just requires the right birder in the right place to turn them up. It seems as though a significant number of the week's vagrants and rarities are the result of CBCs. As good a reason as any to get out out and participate.
