Black-throated Sparrow (Amphispiza bilineata), Big Bend National Park, Texas. Black-throated Sparrows are common but their populations declined by 42% between 1970 and 2014. Population changes could be due to drought, Brown-headed Cowbird parasitism, habitat loss due to urbanization, or fire suppression.
