4,800 pairs of breeding kingfishers, 160,000 'territories' of breeding pairs of jays (RSPB), so jays are far more common over all, but nearly as hard to see. Jays plant a lot of our oak trees, since they bury acorns and sometimes don't find them again; there's a mysterious young oak in this garden, growing in a bed, that must have been planted by one as there's no other oak for two hundred metres.
Not seen a kingfisher for a while. You must have great patience and stillness, or a lot of kigfishers, rowan ! Water quality is improving in our rivers; we have native crayfish in ours (the Granta, near Cambridge) and far more fish than we used to have; so it may be that kingfishers are on the increase.
