Pretty much every evening for the last few weeks we have had many (up to about 50 on some occasions) birds flying over our home in Nottingham, in what I think is an East-West direction. Their cry is Gull like. In the morning I have seen what I assume are the same type of bird flying back in the opposite direction. Not sure what they are or where they may be heading to and from. Sorry about photo quality - there are a long way away!
