Blue Crane

One of the smaller crane species, Blue Cranes are four feet tall and weigh about eleven pounds. Body plumage is silvery bluish gray becoming darker on the upper neck and the lower half of the head and nape. Blue Cranes are one of two species of cranes that do not have bare, red skin on their heads. The feathers of the crown and forehead are light grayish white, while the cheeks, ear coverts and nape are dark ashy gray, which they raise (or fluff) during threat displays, producing a distinctive cobra-like look. Blue Cranes have short bills and black legs. The primary feathers are black or slate gray. The tertial feathers of the wing are long, dark and dangle nearly to the ground, giving this crane an elegant appearance. Males and females are virtually indistinguishable. Juveniles are slightly lighter blue gray than adults, and lack the long wing tertials.
