Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Predominantly grey body plumage, with white and chestnut wing coverts. The primary and secondary flight feathers are black. The most striking feature is the golden-yellow, stiff, bristle-like crown on the head. There are also prominent white cheek patches, bordered by red on the upper part, and a bright red gular sac (throat wattle) that inflates during display.

2. 2

   Beak shape

   Shape and color of the bill: a key field mark.

   Relatively short, straight, and dark grey to black.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Pale grey to blue-grey

4. 4

   Leg color

   Leg and foot color.

   Black

5. 5

   Distinguishing features

   Standout features that separate this species.

   Golden crown, white cheek patches with red upper border, red gular sac, and long black legs. Unlike other cranes, they have a long hind toe which allows them to perch in trees.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles have a duller grey body plumage, a brownish head, and a less developed, duller golden crown. Their facial patches are less distinct, and the gular sac is absent or very small. Their eyes are typically brown.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   No significant seasonal plumage changes. The vibrancy of the gular sac may be more pronounced during the breeding season.

8. 8

   Sexual dimorphism

   How males and females differ.

   Males and females are generally monomorphic in plumage, though males tend to be slightly larger. The gular sac may appear slightly larger and more vibrant in males during breeding displays.

Key field marks

• Golden Crown. Look for the unmistakable golden-yellow, stiff, bristle-like crown on the head. This is the most defining feature.
• Facial Markings. Observe the white cheek patches with a distinct red patch above them. This differentiates it from the Black Crowned Crane.
• Gular Sac. Note the bright red, inflatable gular sac (throat wattle) below the chin, especially visible during vocalizations and displays.
• Body Plumage. The overall body is grey, contrasting with the white and chestnut wing coverts and black flight feathers.
• Legs and Posture. Long black legs and an upright, elegant posture. Look for its ability to perch in trees, which is unique among cranes.
• Vocalization. Listen for its deep, booming 'maa-hem' call, often given in duet, which is characteristic of the species.
