features
The rooster reaches a height of 66 to 73 cm and a weight of 790 to 1140 g. Its crest is red and finely jagged. An important distinguishing feature is the light yellow center point in the cock's crest. The hen reaches a weight of 510 to 625 g. The Ceylon chicken is closely related to the Bankiva chicken .
Way of life
Like most pheasants , the Ceylon hen lives on the ground and feeds on seeds, insects, and fallen fruit.
Tailless mutant
In 1868, the British naturalist Charles Darwin falsely denied the existence of a tailless mutant of the Ceylon chicken, which the Dutch zoologist Coenraad Jacob Temminck had described in 1807.
