Hi Mick - there must be closer SEO's to you!? Have you been on to Beeley or Leash Fen recently? If you drive out of Chesterfield and head towards Upper Loads for example, there is plenty of good habitat out there. I havent been for the past few weeks, but they have been on the "triangle" and last winter they were superb on Leash Fen - saw 4 one afternoon and the GG Shrike! I took my eldest son with me who is 10 and he saw them all too - now his favourite bird.........you can also bird this area from the car, which brings me onto Bennerley..............
This area you cant really do from a car and involves some leg work. It used to be a great area and I belonged to a Bennerley group that met regularly to protect the area and raise funds etc.
There will be people on here who can better point out the access points, but basically anywhere from the Erewash Meadows DWT reserve right up to Ilkeston. I have seen the SEOs at the DWT reserve (and this is great for Barnies especially around the new fishing club) and also further up on Bennerley reserve itself. On that occasion I went with two local guys (one of which is a vol warden) and we parked outside Eastwood and accessed from here (I didnt pay much attention to the road Im afraid). I have also used a track that is right after KFC at Langley Mill and then another from the canal towpath near Cotmanhay (where the Waxwings get!).
The issue with SEO is that they do wander, and this is some area to cover.
I am not sure if these ramblings help, but if you are going then concentrate on the habitat, rather than specific location. They love grassy areas (voles are the key) and there are plenty of unkempt such fields around the walk. I have never started at the football ground by the way, and think that you may be some way out there.
Best of luck, Dan
