July 20, 2015 – Black-tailed Gnatcatcher (Polioptila melanura)
Found in the southwestern United States and northern Mexico, Black-tailed Gnatcatchers are one of the smallest North American songbirds, weighing only 0.2 ounces (5.1-6 grams). Living in very dry habitats, they get the majority of their water from the food they eat, which is mostly insects, along with occasional fruit and seeds. Both males and females build the nest, using materials like plant fibers, cactus wool, spiderwebs, feathers, or fur. They form monogamous pairs and may defend territories together all year, with some pairs staying together for life.
