A couple of years ago, we rented a cottage down a track in the middle of nowhere in Pembrokeshire. The garden was a delight, and full of all manner of birdlife, including goldfinches, chaffinches and bullfinches. The cottage had a conservatory, which was a great place to sit and sketch and observe the birds. (Or just fall asleep in the warm sunshine.)
One evening, just as The Husband had gone off to collect The Daughter and friend from the station, I opened up the windows in the conservatory, made a cup of tea and sat down to read. After a few minutes, I glanced across to one of the open windows and watched two coppery wrens hop inside to join me. As I stood up to close the door into the cottage, one wren beat a hasty retreat back through the open window. The other however, took refuge among the leaves of a grape ivy which grew inside the conservatory, completely lining the roof. And there s/he stayed for an hour or so, apparently unable to find the way out through the open door or windows. The image stayed with me, and I thought the wren amongst ivy leaves might make a good linocut image to try.
