On the heels of spring’s arrival, a wattled crane Bugeranus carunculatus chick hatched at the Smithsonian’s National Zoo March 20, the third of its kind in the park’s history.
…crane chicks sport yellow downy feathers and very small wattles—flaps of skin that prominently hang  beneath the beak of adult birds… the size and shape of a wattle says a lot about a bird’s comfort or stress level. These cranes tend to extend their wattles when they are agitated or trying to assert dominance, and they will constrict their wattles when frightened or submissive.
Measuring 6 feet tall, the wattled crane is… listed as vulnerable on the International Union for Conservation of Nature’s Red List of Threatened Species due to hunting, agricultural advancement, pest control and collisions with power lines.
