If so, does the selection of the present roost, wherever it may be, mean that they are considering another nest? If so, do they consider the last one sufficiently unsatisfactory to impel them to build another? Etc....etc . The young birds were last fed a little after sunset, then they went to sleep as they presumably do when at home. I carried them into the house about six and they woke up, and preened a little and looked around curiously, but they did not ask for food.
