I am inclined to think that the nest may be considered ready for eggs. In previous instances, where witnessed at all, the copulatory act has been seen only about sunset and on completion of the nest. I intended to look for it yesterday, but did not do so. I shall watch later on this afternoon. Copulation. 5:55.
