Just got back to all ur messages after a very busy 4 day shift. I'm thinking its the street lights then. Agree that sparrows aren't seen to much now which is a big shame cos they're such sweet little birds,used to love going to my mums house,she used to get lots of different birds including robins which I never see here. I love watching n listening to birds it helps me cope with my busy life!
I've got another 'keen'... Ouch!
