Two birds we don't see much of in North Wales

Whilst back in St Helens this weekend I went around some of my old haunts, The Lancashire Mosslands around St Helens (now Merseyside and I was getting a few photos as I went). Birds like Corn Bunting, Grey Partridge, Yellowhammer, Tree Sparrow, Skylark and Lapwing are all still around there and seem to be hanging on OK. Some of these are birds we would struggle to see in North Wales and we would have little or no chance of Corn Bunting. Are there still any pairs on the borders or have they dried up now? Grey Partidge are pretty scarce on Anglesey and I haven't seen one here for years. There was a recent sighting near Llansadwrn but otherwise they probably hang on at Bodior and possibly Dulas, Bodorgan, The Braint Estuary fields and maybe around Aberffraw, Maelog, Trefor and possibly Gwalchmai. Any records would be much appreciated!
