Decided in the end to go for the Rose-coloured Starling in Crawley and it showed very well in the tree near no.10 Beachy Road. It's moulting fairly heavily and if it hangs around could turn into something pretty spectacular.
White-fronted Geese still at Amberley on the way back, couldn't find the Bean Goose though:
Grey Wagtail at Lidsey SF:
Siberian Chiffchaff, probable anyway, at Lidsey. All black bill, legs, very pale underneath, yellow/olive restricted to wing edge, prominent supercillium, brownish wash to cheek:
