Artificial lighting disrupts the functioning of specific organisms such as birds, fish, bats and insects. Observations have shown that too much artificial light, especially coloured light, can have a huge impact on nocturnal species, misaligning their circadian rhythm. Animal preference for nocturnal activity may be due to factors such as: avoiding predators, aversion to heat, safer feeding or reproduction. Also changes in the intensity of ambient light at night
may lead to problems with reproduction, avoidance of suitable habitats, changes in seasonal migration routes, and to a reduction in numbers or even the extinction of certain species.
