Light pollution luring birds into cities during migration

Today’s Video of the Day comes from the University of Delaware and features a look at how nighttime light pollution is luring birds into urban areas during migration.

From an evolutionary standpoint, generations of birds have been migrating seasonally for millions of years, while brightly-lit cityscapes have only been in existence for about 100 years.

Researchers have now found that birds are attracted to these bright cities, even though they provide much less in the way of food and habitat crucial to the birds’ ability to complete the migration.
