Image for: Light is the friend of lovers: Artificial night lighting affects songbird behaviour and reproduction


Too much light: Artificial lighting at night leads to the males of certain  species of songbirds starting to sing earlier in the morning. At the same  time, female blue tits start to build nests earlier while male blue tits  allow themselves a bit on the side.
