Grey Plover

Hi. Totally new to this. Apologies for greenness. Yesterday I saw what I think was a grey plover in the local supermarket carpark. It fell to tarmac looking a bit dazed. Seemed smallish and very grey white. No brown beige. Not seen these around here before, at this time anyway. Cognizant of gales recently. Am I way off the mark? I should add I'm down in the Channel Islans.
