The Blue Crane, Anthropoides paradiseus, is a striking bird known for its beautiful plumage and regal stature. This species is also commonly referred to as the Stanley Crane or the Paradise Crane.

In this article, we will explore everything about this majestic bird, including its identification, plumages, molts, and similar species. Identification:

The Blue Crane is a large bird with a height ranging from 100-120 cm and a weight of 4.5-6 kg.

The male and female Blue Cranes have similar physical traits, with the males being slightly larger than the females. Field Identification:

Identifying the Blue Crane is easy since they have a unique appearance compared to other crane species.

They have a striking blue-grey plumage on their neck and wings, a white belly, and long legs. They also have a bald red patch of skin on their head, and their rounded wings end with distinctive black tips.

The Blue Crane has a long, thin beak that is perfect for picking up small animals and insects. Similar Species:

The Blue Crane shares some physical features with other crane species such as the South African Crowned Crane and the Grey Crowned Crane.

However, the Blue Crane can be differentiated through its distinct blue-grey plumage and the black wingtips. Plumages:

The Blue Crane has two main plumages; the adult and the juvenile plumage.

The adult Blue Crane has the striking blue-grey plumage that starts from their head and extends to their wings. Its white belly contrasts sharply with the blue-grey feathers.

On the other hand, the juvenile Blue Crane has a golden-brown plumage, which they lose after their first year. Molts:

Birds molt their feathers in a particular sequence throughout their lifetime, and the Blue Crane is no exception.

The juvenile Blue Crane undergoes its first molt in their first year, where they lose their golden-brown plumage and start growing their adult feathers. After reaching adulthood, the Blue Crane goes through an annual routine molt where they replace old worn-out feathers with new, fresh ones.

During this period, the Blue Crane may appear scruffy and as though it has lost its good looks, but this molt typically takes between six to eight weeks.

In conclusion, the Blue Crane is a beautiful bird species known for its striking blue-grey plumage, long legs, and regal stature.
