Most organisms synchronize life history events with natural photoperiod, of which birds provide a great case study. In a changing environment that includes the rapid growth of artificial light at night (ALAN), it is imperative to understand the mechanisms and feedback loops by which photic input is received and interpret, and how ALAN might interrupt those systems. In Chapter 1, I use a large citizen science database to model how natural photoperiod shapes the clutch size of Eastern Bluebirds. I found that daily changes in photoperiod are the strongest predictor of Eastern Bluebird clutch size patterns. In Chapter 2, I conduct a field experiment with Barn Swallow nestlings to see how they develop morphology and physiology under ALAN. I found that nestlings develop morphology slower and tail feathers faster in ALAN, although ALAN had no impact on physiological measurements or body condition, or brood success. Finally in Chapter 3, I synthesize case studies on skyglow and its impact on ecology, as well as explore potential solutions to mitigate negative physiological effects on birds.
