“The migration forecast maps on BirdCast back up our own Action Alerts with science,\” said Houston Audubon conservation director Richard Gibbons. This window of “peak migration” was chosen after scientists analyzed migration frequency and intensity using more than 20 years of data from the U.S. \”This means turning off or reducing lighting during a window of time when at least 50% of the overall spring migration traffic is moving through the Houston, Dallas, and Fort Worth areas.\”īirdCast migration forecasts can predict nights of intense migration up to three days in advance. \”We have a real opportunity to make an impact here-to help to protect one of the planet’s greatest mass animal movements, just by turning off unnecessary lights,\” said the Cornell Lab’s Julia Wang who is heading up the Lights Out Texas study. Most migratory birds fly at night, and the bright lights of commercial and residential buildings attract and disorient them – causing collisions or exhausting them and leaving the birds vulnerable to threats on the ground.Īs many as 1 billion birds die from building collisions every year.
