Due to the street lightening Magpies’ sleep time was markedly decreased, where some birds are known to sleep.

According to the first research to look at neurological activity in animals thought to be affected by light pollution. The street light might a very bad impact on the sleep pattern of birds,

The researcher did this research with the miniature sensors to collect the pigeons and magpies’ brain activity on three nights in an indoor aviary. the birds have been uncovered to lights with the same depth to road lights earlier analysis has recommended, the latter of which can have much less of an impact on sleep patterns

Both rapid eye movement (REM) sleep and non-REM sleep has been influenced by the lighting. But with the white light Magpies has been more affected comparison to amber light, they losing roughly 76 percent of their non-REM sleep and pigeons loss approx 4 hrs of sleep,  no matter the kind of light.

Because of that, most birds could not sleep at night especially under lights, but according to the study, some of the wild pigeons and magpies have been found to sleep under a street light. The University of Melbourne and La Trobe University, Australia, who co-authored the study ‘ Farley Connelly’ said in a statement, “We have even seen pigeons roosting directly opposite bright white security lights,” The resulted of Disturbed sleep for the birds would depend on whether they can get used to light at night.

The co-author Anne Aulsebrook, also at the University of Melbourne and La Trobe University says “Sleep loss may cause issues for behavior, well being and growth, so if birds can’t adapt or tolerate gentle at night time, they could endure poorer well being, produce fewer offspring or have to seek out new habitats,” says.
