Thanks Geoff. The Avifauna records bigger flocks of LBC but although they are regular here I rarely see more than 3 or 4. I always trawl through the kite flocks for other raptor species. Sometimes there are common buzzards but usually nothing more. I am intrigued how my new home will be for birds. I have already seen Dusky warbler in the garden. When we move I will start an "official list".
