Not easy to spot sometimes…there are always one or two more in the group when they fly off in alarm. The orange beaks give them away. This was painted on a flat stone found on the beach. A piece of iron too…the binding medium is rabbit skin size. True gesso involving chalk with the size forms the base upon which I build. The surface is sealed to protect it from the air. This piece is presented on limed board, framed but without glass. 38x29x6cm framed dimensions.  I’m happy to send a photo of the presentation. The cost of postage is not included in this price. I’ll be in touch to discuss options.
