Disrupting the birds' light and dark cycles can impact circadian rhythms, eventually harming sleep patterns. Biologist Thomas Raap conducted a study which suggested that exposure to ALAN affected the sleep behavior of Eurasian blue tits (Cyanistes caeruleus). [7] In this study, birds woke up earlier due to ALAN factors such as seasonal timekeeping.
