Same here Tilly (Derbyshire) but it's very early. The blackbirds are fighting, I've a pair of robins, collared doves, wood pigeons, squirrels(!) to mention a few and they're all in a feeding frenzy.
The blackbirds and some other very sweet birds have been singing all night everynight for the past couple of weeks, it's crazy (got a stinking cold/cough so I haven't been sleeping).
I'm hoping it's going to be a long courtship, if they start too early and we have a cold snap it'll be a shame for any early chicks.
