Gwen and Stephen are now sorting construction materials for their nest. Gwen has some sort of secret algorithm for deciding which sticks are Acceptable and which are Not. Those that pass the test are carefully placed on the shelf in their back enclosure; the rest are strewn around to indicate their profound inadequacy. Today I produced some horse hair, kindly provided by Super Colleague Joe and his Super Fiancee Veronica. Crows construct an inner cup in their nests that are lined with soft materials, including animal hair, to protect the eggs and then the chicks. Gwen will only allow the finest materials to touch her chicks. Here is a shot of her examining the merchandise.
