me and my dad went off to hartlepool today . we somehow managed to get to a nature reserve with a strange name next to a cemetry . notable species include ringed plover , redshank , knot . moved on to the heugh battery. notable species : common scoter and black throated diver another birder was there . he said he had reports of the red necked grebe but he said no joy. a few lifers. no photos . havent got a good enough camera. we went to a chip shop just down the road . produced the best chips i've had for ages !
Pretty much the same for me as well. I was there this afternoon.
The reserve you mention is Spion Kop nature reserve and the Jewish Cemetery - a good spot of migrant watching.

Approaching dusk a Fox wandered across the common and at 4.50pm a Barn Owl appeared by the first layby. Other birders on the power station road also saw SEO x2 and a Woodcock. Apparently one of the power station police has been taking photos of the BO on his mobile - it just sat on a post whilst he put the headlights on it and took a photo - at around 3:00am mind you!
