Slender, long-beaked bird in my garden

Hi All,

This bird has been in my garden for a couple of weeks...whenever I've spotted it, it's always been on the ground, often hanging around the pet rabbit's outdoor run! It's about 3/4 acre garden, with hedges, trees & shrubs, surrounded on three sides by north Lancashire farmland.

There were a couple of blackbirds feedng in the same area, and this is similar in size, though slighter in build. He/she was not going to be intimidated by the rather territorial blackbirds! There's a noticeable dark patch in front of the eye, and the beak is quite long and slim. This bird spent a lot of time with its head down amongst the abundant clover, selfheal and other "weeds" in my lawn.

I've tried the identification guides, but with no luck. Can anyone help me out?
