Share:

Description

Adults – pale bluish grey body plumage, long white feather plume stretches from eye to beyond the head, long black feathers hang from breast, reddish-orange eyes, black legs, short bill.  Males are very slightly larger than females.  Juveniles – pale ashy gray, with nearly white heads, gray tufts on the ear coverts.

Classification

Class
Aves
Order
Gruiformes
Family
Gruidae
Genus
Anthropoides
Species
A. virgo
Conservation Status
Least Concern

The IUCN Red List describes Anthropoides virgo as a species of Least Concern with a global population of well over a quarter million individuals and increasing.

Social Life
Demoiselle cranes are migratory and largely gregarious, though become more solitary during the breeding season. When migrating and shortly before pairing off for breeding and nesting, cranes congregate in groups of up to 400 and when overwintering, group sizes can swell into the thousands.

Habitat and Range
There are six main populations of Demoiselle Cranes occurring in over 47 countries throughout the world. The three eastern populations occurring in eastern Asia, Kazakhstan/central Asia and Kalmykia (between the Black and Caspian Seas) are abundant, numbering in the tens of thousands. There are also three remnant populations occurring near the Black Sea and Turkey.

The two wintering ranges include India and surrounding countries and northwestern Africa centered in Sudan.

The demoiselle crane lives in a variety of different environments, including desert areas and numerous types of grasslands. When nesting, they prefer patchy areas of vegetation tall enough to conceal them and their nests, yet short enough to allow them look out for predators while incubating their eggs.

Diet
Demoiselle cranes are omnivores. They eat plant materials, especially seeds, insects, peanuts, beans, other cereal grains, and small mammals.

Lifespan
About 27 years in captivity, with records of a few cranes living to 67 years of age. Lifespan in the wild is unknown.

Reproduction
Sexual Maturity: Can be as early as 2 years of age, but more typically is 4 to 8 years.
Mating Season: Spring, usually April or May, but is dependent on the rainy season.  Cranes are monogamous, unless the union does not produce any chicks.
Incubation: 27 to 29 days
No. of Young: A clutch is typically two eggs.  The eggs are spotted and brownish, to blend in with the ground. Chicks fledge at 55-65 days, the shortest of any crane.
