Zippy and I just took Emma for a walk around our neighborhood. As we walked, we noted the bright, outdoor lights shining on the marjority of houses we passed. It was a relief whenever we passed dark houses. A break for our eyes.
As annoying as those bright lights are for me, they can be life and death for birds during migration time. (And yes, I understand that lights on tall buildings are more problematic for birds than suburban lighting.)
I still wish that all people, both urban and suburban, worried less about what might be lurking in the dark, and more about the well-being of our feathered friends. Excessive lighting is just that.
