Light pollution and birds

"Artificial lighting and noise alter biorhythms of birds"

"Noise from traffic and artificial night lighting cause birds in the
city centre to become active up to five hours earlier in the morning
than birds in more natural areas. These were the findings from an
investigation conducted on 400 blackbirds in Leipzig by the
interdisciplinary research group 'Loss of the Night'. Scientists from
the Helmholtz Centre for Environmental Research (UFZ) reported in the
open-access journal PLOS ONE that these findings showed how ambient
noise and light pollution caused by humans have significant effects on
the behavioural patterns of city blackbirds, affecting their natural
cycles."
