Ever since I put up a sign next to the driveway with a picture of a guinea, our neighborhood pet guinea "Carl" sits by it all the time. He is a lone male who appeared in our neighborhood two years ago and never left. He abandoned his daytime ground nest that had a shiny ball to go sit by the sign. Has anyone else seen something like this? Is he lonely or just attracted to the shininess of the sign? Does he recognize the picture as another of his kind?
