1 billion birds a year killed by US skyscrapers

New research has revealed just how dangerous tall, reflective buildings are to wild birds in large cities.
While it is certainly no secret that skyscrapers cause a significant number of bird deaths, scientists now believe that the avian death toll could be as much as one billion birds per year.

The skylines of Chicago and Manhattan are particularly deadly, especially to migratory birds.

"They wind up landing somewhere that's unfamiliar, like a sidewalk somewhere," said conservationist Susan Elbin. "Then when daylight comes, and they want to get more food, they'll fly into a tree that they think is a tree, and it's really a reflected tree in some glass building."

"Then they'll slam into the glass, and then they die."

The problem is exacerbated by the fact that most birds migrate at night when it is cooler and are drawn towards the bright lights of the cities.

"Every time new scientific literature comes out, we learn more about the problem, and... we can pinpoint the best solutions using the science," said conservation biologist Kaitlyn Parkins.

One way that the number of bird deaths could be reduced would be to turn out the lights at night during certain migratory periods - a practice that some states have already started to adopt.

Implementing 'bird-friendly' building designs could also help to reduce the problem as well.

Ultimately though, it could simply be that skyscrapers and migrating birds just don't mix.

Well, I don't live in a country with skyscrapers so I wouldn't know, but are there heaps of dead birds at the bottom of these skyscrapers every morning then, all around and by the entrance, like some kind of mass grave?

An Den?  An What?  I have no particular hatred for any living creature but I also have other things to worry about than unfortunate birds...

This is very concerning. In addition to other issues accelerating the depopulation of birds, we may end up with the Mao Zedong effect. Without a balanced number of natural predators for incests, we can see farming impacted, and the ecological balance of the food chain knocked pretty harshly. The results, of course, can be simulated, we may not even know the full extent of what the eventuality is we do not find a solution for an ultra-infrastructured civilization to co-exist with nature

Seriously doubt these figures, if a billion birds died flying into tall buildings, the ground around them would show the evidence.

as someone who works with skyscraper in Manhattan, for almost 2 decades i do not buy it for a second.   if this was the case, our cleaner crews would be picking up dozens if not hundreds of dead birds a day, but they do not,

Even if this was true, I wonder what the breakdown is in birds per building.  Also breakdown by species.  I imagine the majority would be pigeons, since they seem to be the dominant bird in urban environments.  In general they are a nuisance so other than the mess it would be no great loss.

US skyscrapers kill up to 1bn birds a year   meanwhile billions more birds are born....

That would be about 30 birds per second crashing into US skyscrapers, pretty astounding.
