May 11 was Colorado’s Migratory Bird Day, celebrating the nearly 500 species that live in the state or pass through it. Local naturalist, birder and author Evelyn Horn has spent the past twenty years or so focused on birds. In 1989 she and her husband Al moved from Las Vegas to Eckert and settled near Hart’s Basin, or Fruitgrowers Reservoir, which is controlled by the Orchard City Irrigation District (OCID). People had just been banned from the reservoir because of e-coli, and the absence of human activity made it more attractive to birds.
