Common Crane (Grus grus)
The Common Crane is a large, stately bird
and a medium-sized crane. It is 100–130 cm (40–52 in) tall with a 180–240 cm
(71–96 in) wingspan. The body weight can range from 3 to 6.1 kg (6.6 to 13.4
lb), with the nominate subspecies averaging around 5.4 kg (12 lb) and the
eastern subspecies (G. g. lilfordi) averaging 4.6 kg (10 lb). Among standard
measurements, the wing chord is 50.7–60.8 cm (20.0–23.9 in) long, the tarsus is
20.1–25.2 cm (7.9–9.9 in) and the exposed culmen is 9.5–11.6 cm (3.7–4.6 in).
This species is slate-grey overall. The
forehead and lores are blackish with a bare red crown and a white streak
extending from behind the eyes to the upper back. The overall colour is darkest
on the back and rump and palest on the breast and wings. The primaries, the
tips of secondaries, the alula, the tip of the tail, and the edges of upper
tail coverts are all black and the greater coverts droop into explosive plumes.
This combination of colouration ultimately distinguishes it from similar
species in Asia, like the Hooded and Black-necked Cranes. The juvenile has
yellowish-brown tips to its body feathers and lacks the drooping wing feathers
and the bright neck pattern of the adult, and has a fully feathered crown.
Every two years, before migration, the adult Common Crane undergoes a complete
moult, remaining flightless for six weeks, until the new feathers grow.
It has a loud trumpeting call, given in
flight and display. The call is piercing and can be heard from a considerable
distance. It has a dancing display, leaping with wings uplifted, described in
detail below.
