The Lights Out program encourages the owners and managers of tall buildings to turn off or dim their decorative lights. As a result, many of them die from exhaustion or after colliding with a building. Lights from tall buildings can disrupt these migratory paths, causing birds to circle buildings repeatedly. If you are unable to turn off all outdoor lighting, consider installing motion sensors or warm lighting and installing light shields so the light is only cast down, instead of all around which affects the birds more.During their migratory season, millions of birds representing hundreds of species fly through our city on their way to their summer or winter homes. If you are inside with the lights on, close the shades to prevent inside light from flooding outside. Porch lights, outbuilding lighting along with lighted paths and decorative lighting should be turned off. During peak migration from March 15 – May 31 and August 15 – October 31 turn off the lights from 11:00 p.m. This is where you can help! Something as easy as turning off the lights can make night migration safer for the birds.
Cities with tall buildings are one of the main obstacles for birds, but even outdoor lighting from homes contributes to light pollution and can cause harm. Birds can end up colliding with buildings and windows causing injuries or death or circle the building reluctant to fly from the light resulting in exhaustion and even death. Tall lighted buildings can easily draw them off course and disorient the birds. Many birds use stars in the night sky to help them navigate their way. Although there are these advantages to night travel, it also comes with the dangers of light pollution that can cause disorientation, collisions, and undue exhaustion for the birds.
Traveling at night has some advantages such as calmer skies from less weather events at night, cooler temperatures, and the less likely chance of encountering raptors, like hawks and falcons, who migrate and hunt during the day. Over 250 songbird species migrate at night in an effort to make their journey a little easier.
Each Spring and Fall millions of birds embark on the treacherous journey of migration.
