Had a great day, started at castle lake, first time able to find it. 3+common sandpipers, little egret, 15+little grebe all staying together, thats the most we've seen all in one place. Gadwall, 4+ringed plover, possible wood sandpiper, (can anyone else confirm? still beginner and waders are tough, was only bird field guide looked like?) We then had a hour or two at whitburn obs, door locked as no other birders, have not got key(any help with that would be great) Black throated diver, artic skua, manx shearwater, little gull, lots of auks. Lots of waders moving, three knots right next to hide. Was getting late so decided to head home,Kieran my son(10) noticed a lot of waders next to firing range, closer inspection found 50+ ringed plover, 30 curlew, large numbers of sandling and dunlin on field next to obbs, field behind shooting range held huge numbers of waders. We walked around to get a better look, the birds were spooked by three horse riders, the sky was darkened 3000+ golden plover, 100+ lapwing, what an amazing sight, we have read about it but never seen it, for new birders golden plover was a new tick and what a way to get it!!!!! Would really appreciate info for when other birders are sea watching, We can spot the birds far out but not sure what we are looking at, guess that comes with experiance and help plse.
