Superb Cockatiel

Superb Cockatiel or the Glossy Cockatiel, Nymphicus superbis is a species of cockatiel found throughout Europa. It is closely related to the Common Cockatiel and may have evolved from it.

Description
The Superb Cockatiel resembles the Common Cockatiel, but is smaller at 10 - 11.5 in long and with a wingspan of 18 - 20 in an with a weight of 2 - 3 oz. It closely resembles the Cockatiel but is darker, with a glossy plumage on the back and wings, black wings and large white shoulder patch and orange cheek patches. Males have a lemon-yellow head, throat, crest, face, and cheeks, while the females faces are pale yellow with dull orange cheek patches. The glossy iridescence depends on the angle of the light and may not be seen when the bird is in the shade; when seen however, it is a lustrous and glossy bright pink, purple and oil-green.

Domestic Superb Cockatiels are white and yellow (lutino), pied, pearl and some without orange cheek patches but all varieties have the glossy back and wings.

Calls
A rolling weero-weero... not unlike the Cockatiel, but harsher.
