A Silver Pheasant at a zoo in Bombay has undergone a rare sex conversion, stunning zoo officials.
Although no anatomical changes have occurred, the once dimunitive female bird with dull brown feathers is now larger in size with the typical brightly coloured feathers that males use to attract females. In addition she no longer lays eggs and now fights with her former mate, behaviour indicative of male rivalry. Referring to the change as a case of "sex dimorphism", zoo director Renu Singh says that the incident has surprised most of the staff.
In a rare and a first-of-its-kind phenomenon, a Silver Pheasant, a bird belonging to the peacock family, has changed its sex from female to a male. Confirming this and terming it a kind of “sex dimorphism”, zoo director Renu Singh told IANS that the phenomenon had surprised most of the staff in the zoo.
