Cattle Egret - (s)?

Seeing how there was a 45 minute gap between the last known sighting of the bird at Angle and Derek seeing it fly in "from high" at Sandy Haven, the apparent similarity in plumage, and the fact that the Chapel at Sandy Haven is no more than 4 miles due North of West Angle / Studdock Farm, it could easily be that the bird is roosting at Sandy Haven and feeding at Angle - or there could be two (which would be great)! I'd personally prefer to know that they have been seen simultaneously to confirm the presence of two.
