If I ever start to practice what I preech, the strategy for Spurn (unless it's a real rarity) must be not to chase, and to work a patch. The reality is even with all that list, you may be 2-3 hours just waiting for an Icky. I think you need to pick your birds, decide what you want to see and stay put. In my case it was Icky, (haven't seen one for a few years) and I should have staked a site out.
Golden rule of Spurn - "no plan survives contact with the enemy" - it always reads easier on the pager.
Spot on advice! I have been there 4 days Tuesday-Friday (not staying over as only from Hull) and spent a lot of time chasing shadows like many people over the lst week who as aresult saw very little, particularly Marsh Warblers and Ickys. Had brief views of 1 Icky in Crown car park Tuesday on arrival and a possible Marsh with it and good views of 2 Marsh Warblers, behind Cliff Farm Tuesday and the showy one at Sammy's Friday (still there today). Had good week in bagging male Red-spotted Bluethroat, Golden Oriole in flight several times most days, Ortolan, mostly in flight, 4 male Red-backed Shrikes, 2 Grey-headed Wags, Pied Fly and numerous Spotted Flys, etc, etc. Dipped on RB Fly, no chance of Rosefinch or Serin but cracking Spring birding nevertheless. Heard Bee-eater yesterday.
One local birder I know there just wanders the Point on his own regardless of whats found (no doubt with some exception) and found 2 Bluethroats (one on road driving down!) Thrush Nightingale at Chalk Bank, Quail, to name but a few. I definitely think he has the best system!
Word of warning, those Brown-tail Moth caterpillars really do give you grief, I have a neck like Carlos Tevez at the moment and itch virtually everywhere imaginable. The drizzle on Tuesday prevented their hairs from flying around but now things have dried up, not so! :C
