Abstract
Male starlings which had fully developed testes under 11-h daily photoperiods were subjected for 10 weeks to daylengths either increasing or decreasing by 30 min per week. In both cases testicular regression occurred; in the former case this was complete due to photorefractoriness, and was accompanied by a postnuptial moult and a marked (P J. Endocr.
