SOUTH SALT LAKE — The seasons have changed, and that means it's the time for millions of migratory birds to be traveling to or through Utah in search of important resources, such as food.
Some bird species have already begun this journey while others are still on the way from as far as Central America and South America, said Cooper Farr, director of conservation for Tracy Aviary.
But what you may not know is that many bird species — including flycatchers, sparrows, tanagers, thrushes and warblers — typically make their migration journey at night. As Herb Wilson, a professor emeritus of biology at Colby College, wrote in 2011, these species travel at night mostly for survival purposes.
