Possible Black Swift at Flintkote area

John Bruin, Ter Hurst and I saw a dark Swift in with some White-throated's within the last half hour along Flintkote. We have photos we have to look at on a computer screen. Looked to be too big to be Vaux's, and shape seemed more streamlined than Vaux's. This was a little ways west of the gate.
