Leo Ward Bluebirds of Happiness artist signed hand blown art glass figurines collection

Collection of FIVE hand blown glass blue birds of happiness, each artist signed and dated, as shown. Most I think are Ron Ray? I think one is Leo Ward.

Two large birds, three small birds - these look to me like a happy family, so I've left them all together! All are in very good condition, beaks look good and they have no chips or cracks.
